• Connecting to SQL Server on Parallels Desktop with PHP

  - by Zen Savona

  well I recently bought a Mac and am using it as my primary computer. Because I am required to work with MSSQL via PHP, I have installed Parallels Desktop and run Server 2008 R2 on it. I am using the same mixed mode authentication which I previously had on windows. When I attempt to connect to the server with PHP using either a new test file or my old code, it just doesn't find the server. I have tried running PHP on the XP install with parallels, and using the hostname as COMPUTERNAME\SQLEXPRESS, LOCALIP\SQLEXPRESS localhost localip etc, PHP never finds the server. Also note that I can connect to the database server using Management Studio without problems, so SQL Server is running. Please note that both PHP and MSSQL are running within the virtualised environment. Any contribution is appreciated

• Allow users to view Word documents only and not be able to edit, copy or save them.

  - by Alexander

  Hello In a traditional Windows Server 2003 environment with AD, we have shared a folder for our policy documents (MS Word). These documents get edited/updated now and then by the administrator(principal of college). Users only have read-only access to the folder, but they can still save-as and then change the content. Sharepoint is a possible solution but not easy to implement. We also thought of using a CMS on Linux and installing Joomla to let users only view the docs with a document management system... but is it possible to automatically retrieve the policy folder on the network and convert or put it in a format that users can only view and not copy? We also thought of saving the docs to secure pdf format but the principal wants an automated system. Basically she just wants to work in Word and the policies must be available to staff members on the network. Any ideas? Much appreciated.

• Install Previous Version of PHP Package from Debian Testing Using Apt

  - by Metric Scantlings

  Is there a way to install an older Debian testing repository version of a package using apt-get? Specifically, I am looking to install the latest version of PHP 5.2.x on Debian Lenny. The last time I set up an environment, 5.2.12 just happened to be the version in Debian testing. That was perfect, convenient. Now, testing is at 5.3.x which won't work for my purposes, and my attempts at sudo apt-get -t testing install php5=5.2.12* are answered with E: Version '5.2.12*' for 'php5' was not found.

• Setting up Kerberos SSO in Windows 2008 network

  - by Arturs Licis

  We recently introduced Kerberos (SPNEGO) Single Sign-on in our web-portal, and tested it on a Windows network with Windows 2003 domain controller. Now, trying to test it on Windows 2008 R2 controlled network, SSO just doesn't work due to defective tokens. Up to the moment I was pretty sure that there's something wrong about environment and that were NTLM tokens. We double checked IE settings etc, but nothing helped. Then we checked the following settings for both users (logged on a client test-machine, and the one used as a Service Principal): This account supports Kerberos AES 128 bit encryption. This account supports Kerberos AES 256 bit encryption. .. and error message changed to ' GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256CTS mode with HMAC SHA1-96 is not supported/enabled) It makes me think that Internet Explorer receives Kerberos tokens at all times, and there's just some configuration missing, or it was ktpass.exe to be incorrectly executed. Here's how ktpass.exe was invoked: C:ktpass /out portal1.keytab /mapuser USER /princ HTTP/[email protected] /pass *

• Is it a good idea to have the operating system on a solid state drive?

  - by Kenji Kina

  There is something I don't quite understand. I know a SSD helps with OS load times, but I'm not sure if all this boost is only noticeable/interesting when booting, or gives an all around considerably better experience thereafter. I am interested in having a quick and responsive environment after booting, which leads me to think that it'd be better to spend the SSD capacity in my most used apps (and the page file? Another inside question) and not the OS itself. This, of course, means that I don't know just how much the OS reads/writes its files during normal usage. So, how good an idea is it to dump the whole 20GB+ of Windows 7 OS into the SSD (considering the hefty price per GB of SSD capacity) if I can put up with the usual hard disk boot times? Would I be missing on a lot if I didn't?

• Slow Starting DHCP Client Service - HP Thin Clients

  - by Ryan

  We have recently began adding XPe thin clients to our domain in preperation for a new citrix environment. One thing that has been picked up on in testing is that they appear slow to boot. The issue manifest's it's self as the classic "Applying Computer Settings..." screen we are all used to seeing. After digging into the issue it appears the DHCP Client service is taking some time to load on boot, this varies but I would estimate it can take around 1 minute in some cases. I've eliminated the classic issues, DHCP is responding correctly and in quick time. DNS is not the cause and GPO's are applying promptly. A simple workaround is to assign the client a static IP which work's great so the TCP/IP servies are obviously firing up quickly, just not DHCP Client. Does anyone have any idea's on how I may be able to improve the service start time? Keen to find a better solution before I get my arm twisted into setting up 250 thin clients with static addressing!

• Best Guest OS for running freeswitch under Proxmox

  - by Frank Waller

  We have a lot of asterisk Systems running on dedicated machines and would like to use freeswitch to replace a number of them. One of the advantages of freeswitch is supposed to be that it is doing much better in a virtualized environment than asterisk is. However I can find very little information about people using it in Proxmox containers. I would like to know if anyone has seen any ready to run proxmox images that include freeswitch so we can test a number of things without having to deeply go into creating our own. Or at least a clue to which system images/distro images we can use to quickly get it installed not having to deal with too many dependency or different Linux version issues. Just to be clear: It should be for a more or less current Proxmox and current freeswitch. I am not looking forward to use the KVM mode but would consider it, if it is otherwise ready to run out of the box. I would rather use a real OpenVZ based container. Thanks for anyone helping!

• Apt-Get "sources.list needs at least 1 source-URI" error when building dependecies for Xen

  - by Entity_Razer

  What i'm trying to do is install Xen in a test environment, now I am trying to run the: apt-get build-dep xen-3.3 command, but it keep throwing a error which literally translated from dutch (installed the debian OS in Dutch) say's: E: your sourcelist (/etc/apt/sources.list) has to contain at least 1 source-URI I've googled it but I can't seem to find a definitive solid answer on how to fix this. By default a source-URI (read man page of apt-get) states it needs to be something along the lines of deb ftp://ftp.debian.org/debian stable contrib Now I've got 2 HTTP sources (default Debian ones) up & running so far and they've been working flawlessly for the better part of a few days now. Only now its starting to act up. Anyone able to help me out ? Much obliged !

• How can I make full-screen desktop applications only cover the snapped desktop?

  - by nhinkle

  In Windows 8, you can "snap" two apps next to each other, and one of those apps can be the legacy Windows desktop environment. A convenient application for this (or so I thought) would be to snap a chat client, small browser, or other app while watching content in full-screen on the desktop. The problem with this is that full screen desktop applications will take over the entire screen, even if the desktop is snapped to only occupy 3/4th of the display. What I would like is some way to force "full screen" desktop apps to only cover the snapped desktop area, and to truly go full screen if the desktop is snapped to full-width. Is there some way to configure this? If that didn't make sense, let me illustrate with pictures: Desktop in snapped view with SU chat in mini-browser: What happens when you click "full screen": What I want to happen when I click "full screen" (note this is digitally altered, not a real screenshot)

• VMware ESXi 4 On-Disk Data Deduplication - possible and supported?

  - by hurikhan77

  Environment: We are running multiple web, database, and application servers which usually share a pretty common installation (gentoo linux) and similar configuration in VMware ESXi 4. The differences are usually only some installed features or differing component versions. To create a new server, I usually choose the most similar (by features) running server, rsync a copy of it into freshly mounted filesystems, run grub, reconfigure and reboot. Problem: Over time this duplicates many on-disk data blocks which probably sums up to several 10's of gigabytes. I suppose if I could use a base system as template with the actual machines based on top of that, only writing changed blocks to some sort of "diff image", performance should improve (increased cache hit rate) and storage efficiency should increase (deduplicated storage space). This would be similar to what ESXi already supports for RAM deduplication (page sharing). Question: Is there any way to easily do this on ESXi 4? I already share the portage tree via NFS but this would not work for the rootfs.

• Is an Ethernet point to point connection without a switch real time capable?

  - by funksoulbrother

  In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb

• How to enable an active/active file server cluster in windows 2008 r2 Enterprise

  - by Phygg

  I've just created a cluster for my file servers in Windows 2008 R2 Ent SP1 environment. The goal - an Active/Active cluster for web server data How do I go about telling the cluster to be active for both nodes? Do I have to tell the cluster to be active/active? Here is a link to the instructions I followed when configuring the failover cluster. http://technet.microsoft.com/en-us/library/ff182326(WS.10).aspx So if anyone can help me to grasp the concept or maybe I'm way off and I need a node that is not active along with 2 active nodes to do this, I would appreciate it.

• Diffing file contents

  - by PHeiberg

  I have two plain text files, each file is containing a list of strings sorted alphabetically with one string per line. I want to diff the files and have an output of all strings that exist only in file2. Preferabbly I want the operation to be possible without any 3rd party tools, or with a minimum of installations of tools that is "normal" to find in a windows command line environment, such as GNU Diffutils, Powershell, etc. The output should be in text form (file or as command line output). Example: File 1 contents: A C D File 2 contents: A B C E Result wanted: B E

• Load Balancing a UDP server

  - by Hellfrost

  Hello StackOverflow, I have a udp server, it is a central part in my business process. in order to handle the loads I'm expecting in the production environment I'll probably need 2 or 3 instances of the server. The server is almost entirely stateless, it mostly collects data, and the layer above it knows how to handle the minimal amount of stale data that can arise from the the multiple server instances. My question is, how can I implement load balancing between the servers? I would prefer to distribute the requests as evenly as possible between the servers. I would also would like to have some fidelity, I mean if client X was routed to server y, then I want all of X's subsequent requests to go to server Y, as long as it is sensible and not overloads Y. By the way it is a .NET system... what would you recommend?

• How can I launch RemoteApp on Windows Server from server itself at startup

  - by Rusted

  I have Windows Server 2008 R2 with RDS and custom desktop (GUI) application installed on the server. The app is started as RemoteApp on server by user from his desktop computer (or, sometimes, he can work from notebook over VPN). Some details about environment: the server automatically shuts down every evening and automatically power-on every morning (this is a requirement) desktop application do some precalculations/precaching on startup and it can take lot of time mentioned application have some memory leaks, so I can't use hibernate instead of shutdown When user launching this app from his computer, he can't start work with it until this app finishes pre-initialization. Is there any way to start RemoteApp session at the server startup (without actual user logon), so that the user could connect to this session from his computer later? I don't want to involve the user's computer to make it work. I have tried to do it by Windows startup script, but have no luck - starting RDP session requires actual user session.

• OS X clients ignoring Windows print server permissions

  - by Ilumiari

  I'm in the process of testing a Windows Server 2008 R2 print server for a mixed OS X/Windows environment. Any security permissions (AD groups) I set for the printers on the print server are not honoured by the OS X clients. Only if I remove absolutely all permissions for a given printer will an OS X client not print to that printer. The Windows clients honour the permissions as expected. The PrintService log doesn't record any activity when an unprivileged Windows client attempts to print, and records a typical print job when an unprivileged OS X client attempts to print. Has anyone encountered this problem before and have a fix? With 600-700 clients, a number of which are dual-booting, restricting by IP address is not viable. EDIT: The jobs are definitely going through the print server, they show up in the logs with their AD credentials.

• How to allow an internal server accept remote connections not through RD Gateway

  - by Matt Ahrens

  So, I help administrate a collection of servers running various windows server environments. We have a RD Gateway server, properly configured, to gatekeep for us. It does not have the other servers listed in it's server farm category, though. I just added a refurbished server for a non-profit development environment that is sharing the rack space and port. I would like this server to be accessible via remote connection, but not require RD gateway certification (I cannot add the users for this development server to our gateway since they do not work for the organization hosting the rack.) Is there any way for me to add this dev. server as an exception to which servers should require RD Gateway clearance, or otherwise let users bypass RD gateway credentials for this one machine? Thanks, and let me know if I am misinformed on how RD gateway works or anything. I am still learning.

• Is there an equivalent of SU for Windows

  - by CodeSlave

  Is there a way (when logged in as an administrator, or as a member of the administrators group) to masquerade as a non-privileged user? Especially in an AD environment. e.g., in the Unix world I could do the following (as root): # whoami root # su johnsmith johnsmith> whoami johnsmith johnsmith> exit # exit I need to test/configure something on a user's account, and I don't want to have to know their password or have to reset it. Edit: runas won't cut it. Ideally, my whole desktop would become the user's, etc. and not just in a cmd window.

• Using VirtualBox/VMWare to deploy software to multi sites ?

  - by Sim

  Hi all, I'm currently evaluating the feasibility of using VirtualBox (or VMWare) to deploy the follow project to 10 sites Windows XP MSSQL 2005 Express Edition with Advanced Services JBoss to run 1 in-house software that mostly query master data (customers/products) and feed to other software Why I want to do this ? Because the IT staffs in my 10 sites are not capable enough and the steps taken to setup those "in-house project" are also complicated What are the cons I can forsee ? Need extra power to run that virtualbox instance The IT staffs won't be much knowledgeable 'bout how to install the stuffs Cost (license for VirtualBox in commercial environment as well as extra OS license) I really seek your inputs on the pro/con of this approach, or any links that I can read further Thanks a lot

• Set Default Program for All Users on Server

  - by MattN

  I work with a large server environment that's running Windows Server 2003, 2008, and 2012 now on some boxes. We have a custom-built log viewer program that associates with two file types that I'd like to set to be the default program for all users across all boxes, so new users don't have to set the default program themselves on every box they log into. Ideally I'd like to have a simple registry script we could push out to all machines at once. I realize this likely means changing the registry entries for either HKCR or HKLM for the file extensions, but adding the program location with %1 extension to \shell\open\command value in HKLM simply opens the program and does not also load the log file. Am I just missing an open and play setting, or am I looking at this entirely wrong? (And I know the script will need to be different for 2003 and 2008, but changing the version for two scripts isn't hard) Thanks!

• Gotomeeting MSI needs elevated privs?

  - by DrZaiusApeLord

  Typically I can deploy MSIs with no issue, but the Gotomeeting one refuses to install. SCE lists it as pending and AD just attempts to install it, gives up, and never tries again. When I tried running it by double-clicking its icon, it told me "needs to run with elevated privs." I don't see how I can get AD or SCE to run it with these higher privs. I can run it by using an elevated command prompt and running msiexec from there. The MSI is the one labeled "GoToMeeting MSI Installer (ZIP)" from here: http://support.citrixonline.com/GoToMeeting/search?search=msi Any ideas? I run an environment where the users are non-admins and would love to be able to upgrade this centrally.

• Shared storage solution for our sql server backups

  - by Gokhan

  We have 3 clustered sql servers. We have 5+ multi terrabyte databases and their backup files (compressed using quest litespeed) are hitting over 600gb each, We are required to keep at least a week or two weeks (if we can) of weekly full backups and then 6 days differential backups, and a week or 2 weeks worth of log backups local. We are currently limited to 2TB volumes from our san team, we can have multiple volumes but they are expensive ($200 per raw TB per month) and having to deal with many backup volumes instead of a single big volume is difficult. I think if we could have a shared network storage of 20TB+ raid 10 or so for all our servers for keeping the backups and another department will copy them to tape from the network storage and delete files according to the retention period would be good, if this box would be a build in operating system (even unix a complete file storage system) that would be good. What do you guys think, does this make sense to you, is there any manufacturer that sells a storage product like that which that work in a clustered environment? Thank you

• Gather Outlook/Exchange connection Status responses from script

  - by mrTomahawk

  I'm trying to figure out a way in-which I can remotely gather Outlook = Exchange Connection stats from systems. I know I can have the users Right-click their Outlook icon in the system notification area, and then choose "Connection Status", but I'd really like to be able to poll this information without having to as the user to do anything. I saw this previous post, and I believe what he did is similar to what I'm trying to do we created a VB application that would pull user PTO information from a backend system and send out status emails to each of the users on a monthly basis but I'm trying to do it to gather the connection information from all my sites for certain parts of the day. Ideally I would like to do this via some sort of VBScript code since that is what I'm most familiar with, but I can work with Powershell too. My environment is all Exchange 2003 and Outlook 2003 clients.

And , I 'm using Raid 5 only. How do i provision keeping performance in mind( so that performance hit is not there)?..And i need to understand the concept of meta head as well. Please help me by elaborating the above scenario..I am learning to provision storage in non productive environment( b'fore going ahead and working on client prod server) and i have been learning a lot from SF ...I request the seniors here to help me understand it better.

• How to archive Exchange mailboxes remotely?

  - by amyassin

  We have an environment that is based on an Active Directory domain (running Windows Server 2003 SP2), an internal email system using Exchange Server 2003 (internal mailbox, nothing online), and the clients run a mixture of MS Outlook 2007&2010, with the majority running 2007. Recently we noticed that Exchange server is taking so much space for mailboxes. We are examining some solutions to reduce space, and it seems that we could make use of the archiving feature to archive older messages. I can set the auto-archive option manually for every individual user, but is there any other easier way to automate that task? Is there any feature in exchange server or active directory domain that enables setting that as a kind of policy or something similar, or a script to be scheduled to run by all users?
