• Number of routers in small community lock up and require reboot.

  - by Anthony Hiscox

  I live in a small town which has one primary ISP. Lately I have noticed that a number of wireless routers have been locking up and requiring a reboot before allowing any connections. This has affected two of my routers, my work router, and a few others. In all cases wired continued to function as usual. Often wireless clients can see the SSID but simply won't connect. I can only think of a few possibilities and was hoping someone here might be able to point me in the right direction: Our ISP is well known to be flaky, something they are doing is causing this, what that might be I have no clue it as seems to affect the wireless only. There's a power issue in town, given our remote location and reputation for crap electrical, this seems reasonable. Only one router was plugged in to a UPS, and I'm not sure of the quality. There is some bug in all the different firmware for every one of these routers (all different). That doesn't seem reasonable, unless; it's an unknown (or known) exploit or DoS of some sort being launched by a massive team of ninjas hell bent on forcing us all to be tethered to our walls by ethernet cables or; it's just been a coincidence and I'm just paranoid (this has some weight, I mean read 4 again). Anyone else experience similar issues and have some tips?

• Application runs fine manually but fails as a scheduled task

  - by user42540

  I wasn't sure if this should go here or on stackoverflow. I have an application that loads some files from a network share (the input folder), extracts certain data from them and saves new files (zips them with SharpZLib) on a different network share (output folder). This application runs fine when you open it directly, but when it is set to a scheduled task, it fails in numerous places. This application is scheduled on a Win 2003 server. Let me say right off the bat, the scheduled task is set to use the same login account that I am currently logged in with, so it's not because it's using the LocalSystem account. Something else is going on here. Originally, the application was assigning a drive letter to the input folder using WNetGetConnectionA(). I don't remember why this was done, someone else on our team did that and she's gone now. I think there was some issue with using the WinZip command line with a UNC path. I switched from the WinZip command line utility to using SharpZLib because there were other issues with using the WinZip command line. Anyway, the application failed when trying to assign a drive letter with the error "connection already established." That wasn't true and even after trying WNetCancelConnection(), it still didn't work. Then I decided to just map the drive manually on the server. Then when the app calls Directory.Exists(inputFolderPath) it returns false, even though it does exist. So, for whatever reason, I cannot read this directory from within the application. I can manually navigate to this folder in Windows Explorer and open files. The app log file shows that the user executing it on the schedule is the user I expect, not LocalSystem. Any ideas?

• Why can't I see all of the client certificates available when I visit my web site locally on Windows 7 IIS 7?

  - by Jay

  My team has recently moved to Windows 7 for our developer machines. We are attempting to configure IIS for application testing. Our application requires SSL and client certificates in order to authenticate. What I've done: I have configured IIS to require SSL and require (and tried accept) certificates under SSL Settings. I have created the https binding and set it to the proper server certificate. I've installed all the root and intermediate chain certificates for the soft certificates properly in current user and local machine stores. The problem When I browse to the web site, the SSL connection is established and I am prompted to choose a certificate. The issue is that the certificate is one that is created by my company that would be invalid for use in the application. I am not given the soft certificates that I have installed using MMC and IE. We are able to utilize the soft certs from our development machines to our Windows 2008 servers that host the application. What I did: I have attempted to copy the Root CA to every folder location for the Current User and Location Machine account stores that the company certificate's root is in. My questions: Could I be mishandling the certs anywhere else? Could there be a local/group policy that could be blocking the other certs from use? What (if anything) should have to be done differently on Windows 7 from 2008 in regards to IIS? Thanks for your help.

• SVN hangs on commit - any suggestions for troubleshooting?

  - by Richard Beier

  We're having a problem with SVN... Subversion clients such as TortoiseSVN hang when we commit any more than a few files at a time to our server. Everything appears to actually be committed successfully to the repository; but the client hangs after all the data has been transmitted. We're using version 1.4.4 of the SVN server. We use the svn:// protocol rather than http to connect. We've reproduced this problem with several clients: TortoiseSVN (1.6.10), AnkhSVN (2.1), and the Silk command-line client (1.6.12). This is happening for everyone on the team, though some people seem to be more affected than others. If someone commits only a few files, it often works; but with more than half a dozen files, it usually hangs. Does anyone have troubleshooting suggestions? This has been happening sporadically for a while, but it's become pretty consistent lately. We've been working around the issue by killing the hung SVN client, doing "svn cleanup", and then doing "svn up"; but sometimes that causes tree conflicts. Another workaround is to blow away the workspace and check it out again after every commit; but of course that's pretty annoying. Are there any diagnostics that could help us troubleshoot this? We're considering upgrading to SVN 1.6 server, and installing the server on a new machine; but we're wondering if there's an easier solution. Thanks for your help, Richard

• How I can fix the "Display Driver has stopped responding and has recovered"?

  - by Vitor Rangel

  I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

• mplayer (mplayerhq.hu) repeats ending audio frames

  - by kamikatze

  mplayer (from mplayerhq.hu) on windows repeats the last few audio frames upon exit. When the video ends, before you can see Exiting...

• Pivot Table grand total across columns

  - by Jon

  I'm using Excel 2010 and Power Pivot. I'm trying to calculate confidence and velocity for a development team. I'm extracting some information from our time and defect system each day and building a data set. What I need to do with Excel is do the calculations. So each day I add to my data set 1 row per task in the current project, estimate for that task and the time spent on that task. What I want to calculate is the estimate/actual for each task but also for each person. The trouble is that each day the actual is cumulative so I need to pick out the maximum value for each task. The estimate should remain unchanged. I can make this work at the task level with a calculated measure (=MAX(worked)/MAX(estimate)) but I don't know how to total this up for a person. I need the sum of the max worked for each task. So a dataset might look like: Name Task Estimate Worked N1 T1 3 1 N2 T2 3 1 N3 T3 4 1 N1 T1 3 2 N2 T4 5 1 N3 T3 4 2 N1 T5 1 2 N2 T6 2 3 N3 T7 3 2 What I want to see is for task T1 2 days were worked against an estimate of 3 days - so 2/3. For person N1 I want to see that they worked a total of 4 days against an estimate of 4 days so 4/4. For person N2 they worked 5 days for an estimate of 10 days. Any ideas on how I can achieve this?

• SharePoint 2010 Enterprise wiki - [New page] missing

  - by icelava

  I am trying to ramp up knowledge on SharePoint deployment and usage (never did before), due to a direction to use SharePoint 2010 as a repository platform (wiki format) for our customer's infrastructure documentation. In my test virtual server, a new site of Enterprise wiki template was setup. Went into Site Actions Manage Site Features to activate Wiki Page Home Page. The default sub-web then went from /Pages to /SitePages and looks like the default Team template. The odd thing is the Site Actions is missing the New Page option. My colleague does not understand why this is the case, as it ought to be there. The original /Pages sub-web does have the option. What conditions are in play that influences the appearance of that option? UPDATE Another phenomenon observed is in the Site Actions View All Site Content view, the wiki document libraries listed in the grid will have their hyperlink (e.g. "Site Pages") lead straight to the direct default page. It would not show its own table listing of pages under that document library, unlike the original Pages document library, which expectedly show up as a listing. I wonder if this hints to any problems.

• Standards for documenting/designing infrastructure

  - by Paul

  We have a moderately complex solution for which we need to construct a production environment. There are around a dozen components (and here I'm using a definition of "component" which means "can fail independently of other components" - e.g. an Apache server, a Weblogic web app, an ftp server, an ejabberd server, etc). There are a number of weblogic web apps - and one thing we need to decide is how many weblogic containers to run these web apps in. The system needs to be highly available, and communications in and out of the system are typically secured by SSL Our datacentre team will handle things like VLAN design, racking, server specification and build. So the kinds of decisions we still need to make are: How to map components to physical servers (and weblogic containers) Identify all communication paths, ensure all are either resilient or there's an "upstream" comms path that is resilient, and failover of that depends on all single-points of failure "downstream". Decide where to terminate SSL (on load balancers, or on Apache servers, for instance). My question isn't really about how to make the decisions, but whether there are any standards for documenting (especially in diagrams) the design questions and the design decisions. It seems odd, for instance, that Visio doesn't have a template for something like this - it has templates for more physical layout, and for more logical /software architecture diagrams. So right now I'm using a basic Visio diagram to represent each component, the commms between them with plans to augment this with hostnames, ports, whether each comms link is resilient etc, etc. This all feels like something that must been done many times before. Are there standards for documenting this?

• Best Asp.net Hosting

  - by dotnetguts

  There are many asp.net web hosting companies which spends lot on advertisement and also gives you very cheaper rate, as low as $5, but when it comes to support they are simply hopeless. Everyone can you please pass your experience with your past hosting companies and suggest any good asp.net hosting company? Please consider following requirement factors 1) Asp.net 3.5 or 4.0 supported. 2) Url Rewriter support 3) GZip support (Dynamic through code) 4) Initial Setup support (If required) 5) SQL Server 2005 or 2008 6) Allow to access SQL Server DB using SQL Mgmt Studio 7) Environment supporting Backup and Restore of DB on my own, without involving tech support team 8) Full Text Search support 9) FTP support 10) I can able to send atleast 500 Emails daily. 11) 99.9% Up Time (No matter all web hosting say they have 99.9% Up Time, but its not true). 12) Alert Email to be sent when they do any maintenance or during downtime. 13) Hosting Price should be reasonable. Incase you feel i am missing something please add to the list. Can anyone suggest good webhosting company based on above factors?

• Cannot open root device xvda1 or unknown-block(0,0)

  - by svoop

  I'm putting together a Dom0 and three DomU (all Gentoo) with kernel 3.5.7 and Xen 4.1.1. Each Dom has it's own md (md0 for Dom0, md1 for Dom1 etc).

• git : The remote end hung up unexpectedly - too many simultaneous users?

  - by Pritam Barhate

  I asked this first on StackOverflow and I was suggested that I should ask it here: We have a self hosted git server (Gitolite) on a VPS account (CPU:2.68GHz RAM:1824MB). This same VPS is also used to publish our underdevelopment web apps for client demos. (Very little traffic). so the main use of the server is as a Git Server Only. This git server is accessed by a team of 30-40 people for various projects. Our problem is that during the day when 6-7 people are trying to access the server (sometimes same repo) we get frequent error message: ssh: connect to host xxx.xxx.xx.xx port 22: Bad file number fatal: The remote end hung up unexpectedly After trying for 10-15 minutes it generally succeeds. During early mornings and late nights when there are only 1-2 people, git commands work with 100% success rate. Also I would like to note that if I access the other file hosted on the server through HTTP it works fine. I found a couple of questions on StackOverflow and on other sites regarding this. But most of the people point towards SSH key set up or conflicts between Msysgit and Cygns SSH. However I don't think this is the problem in our case as we get this behavior on Windows (using msysgit only) as well as Mac Machines. Also if it was SSH configuration issue then it shouldn't work at all. But in our case it works after 10-15 minutes. I think in our case it might be too many simultaneous connections to same server (or same repo) or something like that. Does there exists a setting or a conf file that needs to modified to solve this problem? Please help me solve this problem or point me in the right direction. Thanks in advance. Pritam.

• TCP Keepalive and firewall killing idle sessions

  - by Carlos A. Ibarra

  In a customer site, the network team added a firewall between the client and the server. This is causing idle connections to get disconnected after about 40 minutes of idle time. The network people say that the firewall doesn't have any idle connection timeout, but the fact is that the idle connections get broken. In order to get around this, we first configured the server (a Linux machine) with TCP keepalives turned on with tcp_keepalive_time=300, tcp_keepalive_intvl=300, and tcp_keepalive_probes=30000. This works, and the connections stay viable for days or more. However, we would also like the server to detect dead clients and kill the connection, so we changed the settings to time=300,intvl=180,probes=10, thinking that if the client was indeed alive, the server would probe every 300s (5 minutes) and the client would respond with an ACK and that would keep the firewall from seeing this as an idle connection and killing it. If the client was dead, after 10 probes, the server would abort the connection. To our surprise, the idle but alive connections get killed after about 40 minutes as before. Wireshark running on the client side shows no keepalives at all between the server and client, even when keepalives are enabled on the server. What could be happening here? If the keepalive settings on the server are time=300,intvl=180,probes=10, I would expect that if the client is alive but idle, the server would send keepalive probes every 300 seconds and leave the connection alone, and if the client is dead, it would send one after 300 seconds, then 9 more probes every 180 seconds before killing the connection. Am I right? One possibility is that the firewall is somehow intercepting the keepalive probes from the server and failing to pass them on to the client, and the fact that it got a probe makes it think that the connection is active. Is this common behavior for a firewall? We don't know what kind of firewall is involved. The server is a Teradata node and the connection is from a Teradata client utility to the database server, port 1025 on the server side, but we have seen the same problem with an SSH connection so we think it affects all TCP connections.

• Multiple servers vs 1 big server performace

  - by pistacchio

  Hi to all! My team of developers has suggested a server structure for an upcoming project we are developing. Our structure is "logical", meaning that the various logical components of the application (it is a distributed one) relies on different servers. Some components are more critical than others and will be subjected to more load. Our proposal was to have 1 server per component but the hardware guys suggested to replace the various machines with a single, bigger one with virtual servers. They're gonna use Blade Servers. Now, I'm not an expert at all, but my question to the guys was: so if we need, for example, 3 2GHz CPU / 2GB RAM machines and you give me 1 machine with 3 2GHz CPUs and 6 GB of RAM it is the same? They told me it is. Is this accurate? What are the advantages or disadvantages of both the solutions? What are the generally accepted best practices? Could you point out some URL reference dealing with the problem? Thank you in advance! EDIT: Some more info. The (internet / intranet) application is already layered. We have some servers on the DMZ that will expose pages to the internet and the databases are on their own machines. What we want to split (and they want to join) are some webservers that mainly expose webservices. One is a DAL that communicates with the database layer, one is our Single Sign On / User Profile application that gets called once per page and one is a clone of what seen on the Internet to be used on our lan.

• Is Hyper-V server suitable as a desktop testbench?

  - by Thomas.Winsnes

  At the moment we are running a test bench with several desktop computers, that are reimaged every time we need to test on a different operation system. Also because different versions of our software is tested on each image, we have to install our software every time we want to test it. The problem we have had with going with a virtualization technology is that our software is depending on directx/opengl and 3D acceleration, and this has not been something that virtual machines have excelled at. With the release of SP1 for Windows 7 and Server 2008 R2 Hyper-V has gotten better 3D acceleration support, so we are looking into virtualizing our testbench using this. Our test scenario would most likely be something close to this: 1. Remote into the hyper-V server and load the test VM needed for the current tests 2. Remote into the VM and install the new version of the software 3. Run the tests It would be nice, but not essential, if our support team could remote into the VMs to match the users OS+software combination when doing support. Does anyone have any experience with this kind of settup with hyper-v?

• Limiting bandwith on an Windows 7 machine

  - by Mihai Damian

  I need to limit the bandwidth on my Windows 7 x64 machine. In the past (on XP) I've been able to use NetLimiter for similar tasks. However for some reason I can't get it to work anymore. For lower limits the bandwidth tests are able to exceed the limit by 10-50%; higher limits seem to be ignored completely and the bandwidth tests report download speeds of over 10 times the speed I set. I'm using speedtest.net and some similar service from my ISP for these tests. Anyway, I don't necessarily need a program as complex as NetLimiter since I only need to throttle my machine's bandwidth, not a specific program's. In case you are wondering why in the world I'd want to cripple my Internet speed, there is a funny story behind this. Long story short, my modem gets random disconnects. Tech support comes in, says my Internet speed is abnormally high and I must be using some tools to somehow make it go faster than it's supposed to and this messes up my modem. I check the connection with another computer and it seems that my PC is the only one in my network that gets abnormal speeds. I reinstall my OS, speed looks normal at first, after I install the batch of 50 or so updates, it goes back to abnormally high speeds and the disconnect problems are not solved. Now I don't have a clue if the explanation the tech team gave me was just a strategy to lay the blame on someone else, but I was trying to give them the benefit of the doubt and see what happens if I really reduce my speed to their specification. Any help appreciated.

• How is the extra mSATA SSD disk used/configured in a Dell XPS laptop?

  - by Mark

  Some machines in the new XPS laptop range from Dell come with a regular, large (500GB+) HDD and an additional 32GB m-SATA SSD. The only detail I can find about this extra drive on the Dell site is this: Store your important files, multimedia and photos with XPS 15’s large hard drive options. To get instant access to your media, choose an optional mSATA solid-state drive (SSD) that can boot up to twice as fast as a regular hard drive and resumes in less than 1 second. I'd like to know more about how this extra drive is set up and used, specifically: Is anything installed on it (e.g. OS files or a boot loader) or is it just used as swap space? Is the m-SATA drive visible as a lettered drive in Windows? (I'd guess not if it's used for swap file only.) Is this unusual configuration likely to cause any problems later down the line - e.g. when upgrading to Windows 8? As usual, Dell's sales team haven't been able to help. If anyone's actually got a Dell machine with this or a similar hard drive set-up and can give a definitive answer rather than speculation I'll accept the answer.

• Thunderbird 11.0.1 and Lightning 1.3: How do I propose a different time for a meeting?

  - by seaao

  This all happens on my x64 Linux workstation btw. tl;dr: My colleague invited some people and me for a meeting. The meeting was scheduled a week to late. I -wrongfully- accepted. How do I propose a new time? To explain a bit more in detail: I received a meeting request in my mailbox. Thunderbird is so nice to let me accept or reject it, and after I click the button to accept, it is directly added to my calendar. But when I double click on the meeting to edit it, I get a function-wise scaled-down version of the meeting: The only settings I can alter are whether I want reminders, and if I go at all. Trying to drag it to another day doesn't work either: My calendar behaves like read-only (which it isn't btw). There are several questions (without answer...) to be found on Stack Overflow and on the Thunderbird knowledge base about using lightning. But I get the idea that I'm one of the few who won't comply with the team even before the meeting is started. My googling revealed no bugs or feature requests in the direction I'm thinking. A link to an explanation how to achieve this, or another perspective about how to reach the desired goal (meeting with my colleagues and me) would be mostly welcome!

• Simple, centralized user management on a small LAN - NIS or LDAP?

  - by einpoklum

  I'm setting up a small LAN for my team. It will, for all intents and purposes, not be connected to any external networks. I would it to have centralized control of user accounts (at least, I think I'd like that; I'm also considering using puppet, so theoretically I could just push /etc/passwd changes, or something). The number of machines is fixed, but not very small. Mostly they're 'attached' to a single user, but sometimes people work remotely on someone else's box; and there are a couple of servers. I've read this question, but my scenario is much simpler (even simpler than in this question) and I'd like to do something (relatively) quick, with not much hassle, but not a dirty totally-insecure hack. Is NIS relevant for my scenario? If not, what's the most hassle-free way to set up LDAP (or LDAP+Kerberos) to achieve the same? Notes: I have no experience with setting up either NIS or LDAP. We use Debian-flavored Linux distributions, mainly Kubuntu 12.04 (not my choice, but that's the way it is).

• Automatically update SVN repository on another server

  - by Mikey C

  We have 2 Ubuntu web servers, one of which is our staging server (Staging) and the other is our live server (Live). Staging has our Subversion repository, as well as the latest version of our sites on it. Because the SVN server is running on Staging, I've added post-commit hook scripts so that the staging server automatically has the latest code. Easy. However, I'd like one of the repositories on Live to also stay updated. This is a repository of images, PDFs and suchlike. When a team member commits to this, I'd like it to automatically update on the live servers so it can be used in mailings, content managed pages etc. I'd add something to the post-commit to SSH across and update, but for security, we can only SSH from one server to another as user 'commandLine', whereas the 'www-data' user runs the post-commit. I'd rather not run a cron on Live to update every 5 minutes, but I can't see another way of doing it without altering all our user permissions. Any ideas?

• Convert MPG w/ AC3 audio to something else - on a Mac

  - by anonymous coward

  I'm helping with a small volunteer media team, and they have several .mpg videos that don't appear to have sound when played in QuickTime, iTunes, Real Player, etc, on the local Mac machine. I was able to hear audio after transferring one of the movies to a Windows machine that had VLC media player on it. Through VLC I was able to discover that the audio stream is a52 / AC3 format. We use Autodesk Cleaner in our normal workflow of converting the format of our videos to FLV, but for some reason it's unable to convert this particular batch of videos (well, the video converts fine, but with no audio). Obviously, it seems that there's a codec issue here, but I'm not sure how to correct it. (I'm not extremely familiar with Macs, and/or Autodesk Cleaner). I've seen the Perian codec pack, but I'm not sure that having the codecs on the system will enable Cleaner to convert these videos (particularly the audio stream, since the video converts fine). Is there something obvious that I'm overlooking, or will we have to use something else for this particular batch of videos? If so, what?

• windows: force user to use specific network adapter

  - by Chad

  I'm looking for a configuration/hack to force a particular application or all traffic from a particular user to use a specific NIC. I have an legacy client/server app that has a "security feature" that limits connections based on IP address. I'm trying to find a way to migrate this app to a terminal server environment. The simple solution is for the development team to update the code in the application, however in this case that's not an option. I was thinking I might be able to install VMware NIC's installed for each user on the terminal server and do some type of scripting to force that user account to use a specific NIC. Anybody have any ideas on this? EDIT 1: I think I have a hack to work around my specific problem, however I'd love to hear of a more elegant solution. I got lucky in that the software reads the server IP address out of a config file. So I'm going to have to make a config file for each user and make a customer programs files for each user. Then add a VMware NIC for each user and make each server IP address reside on a different subnet. That will force the traffic for a particular user to a particular IP address, however its really messy and all the VM NIC's will slow down the terminal server. I'll setup a proof of concept Monday and let the group know how it affects performance.

• Slower/cached Linux file system required

  - by Chopper3

  I know it sounds odd but I need a slower or cached filesystem. I have a lot of firewalls that are syslog'ing their data to a pair of Linux VMs which write these files to their 'local' (actually FC SAN attached) ext3-formatted disks and also forward the messages to our Splunk servers. The problem is that the syslog server is writing these syslog messages as hundreds, sometimes thousands, of tiny ~4k writes per second back to our FC SAN - which can handle this workload right now but our FW traffic's going to be growing by at least a factor of 5000% (really) in coming months and that'll be a pain for the SAN, I want to fix the root cause before it's a problem. So I need some help figuring out a way of getting these writes cached or held-off in some way from the 'physical' disks so that the VMs fire off larger, but less frequent, writes - there's no way of avoiding these writes but there's no need for it to do so many tiny ones. I've looked at the various ext3 options, setting noatime and nodiratime but that's not made much of a dent in the problem. Obviously I'm investigating other file systems but thought I'd throw this out in case others have the same problem in the future. Oh and I can't just forward these messages to Splunk, our firewall team insist they're in their original format for diag purposes.

• Embedded Windows XP

  - by Kyle

  My company acquired a brake press for bending large structural steel plates. We received it second hand and it came with an embedded copy of windows XP. Now for the part that's driving me nuts: plug and play has been turned off, also accessibility options has been disabled. What does this mean for me? Keyboards will not work! Nothing that plugs into a USB port will work and it does not have a CD ROM drive. I have tried to turn on plug and play using the on screen keyboard but it is not there since accessibility options is turned off. I would just get an updated copy of the the embedded OS but they come from Sweden and are extremely expensive. I assume there has got to be a way to get a USB devices to work. We need to get a wifi adapter on it so I can use team viewer and remotely configure it for our needs. Things to keep in mind: There is no keyboard so everything has to be done with the mouse There is no PS2 port for a keyboard just a mouse. Odd. I am 5 states away from this location and have been working with a tech who is physically installing the machine. System 32 seems to be missing A LOT of files, the tech told me there is only 8 folders in there and no other files (I don't even understand how Windows is running like this). If anyone has ANY ideas I would appreciate it, I am unsure where to go from here.

• Outlook Calendar Attachments to have limited access to just Required attendees

  - by Jason Pearce

  The management team at my company often attaches documents (Word, Excel, PDFs) to their Outlook Calendar meeting requests. The meeting requests are sent to the managers, but also to their assistants. The desire is to have everyone be able to view the full meeting request and its content, but limit the ability to open the attachments to just the managers. Is there a way in Outlook 2003 and/or 2007 to limit access to attachments that accompany meeting requests? Ideally, can access to the attachments be controlled by the "Select Attendees and Resources" window when selecting individuals from the Global Address List. Can those in the Required field have access to the attachments while those in the Optional or Resources fields not have access? My suggestion was to simply place all meeting attachments in a shared network folder that has read/write access limited to managers. They would then just place fully qualified links to those files in the body of the Meeting Request. While everyone would receive and see the links, only a few would have access. This, however, wasn't easy enough for them, so I'm looking for some other ideas.
