• My home box as my own host?

  - by Majid

  Hi all, I have a 512 kb/s DSL service at home. I do not have a static IP but I can get one if I pay some extra to my ISP. Now, if I get the static IP, can I make my home box act as my internet host? What else do I need? Thanks P.S. I know that if at all possible, the site I make available this way might be slow, that is alright, my question is if it is possible at all. Edit: I need this for very small traffic. I am a php developer and for my projects I am often asked to provide a demo. I currently use a free hosting for this purpose but it is down most of the time and support is non-existent. So I thought to set-up my home computer as my test server. With this please note that: I will only occasionally have 'visitors' and that will be one or possibly two visitors at any time. These demos, are to showcase functionality, so no big images are served and page views will normally generate under 100KB of traffic.

• All application passwords lost on Windows 7

  - by Rynardt

  A couple of days ago I changed my Windows 7 login password. My laptop is on my company's domain, so password changes are done over the internal network. Since changing the password I noticed that all my saved Chrome passwords are missing. Also Skype, Windows Live, Internet Explorer and Outlook lost their saved passwords. I guess there could be more applications with lost passwords, but I have not opened them yet. This makes me think that most applications saves their passwords to a general password vault on the Windows system and this vault got somehow corrupted when I changed my domain login password for windows. Do anyone have any idea of how to fix this and prevent it from happening again? EDIT : More Info I do development work at the office, so most of the time I bypass the firewall and connect directly to the internet gateway. Now and then I would connect to the company wifi network to do printing and access files on a NAS. So by default my laptop does not connect to the wifi hotspot. On this occasion to update the password, I had to connect to the wifi. So referring to the comment by OmnipotentEntity below, could this have happened when the system rebooted without a connection to the network as the laptop does not auto connect to the wifi hotspot?

• How to automatically restart Apache service after HTTP 503 error?

  - by Gnanam

  Our production server is running Apache v2.2.4 on CentOS5.2. Mono v1.2.4 is integrated within Apache. Recently, we faced a problem in our production server. From Apache's access_log, I found a HTTP 500 internal server error for one of the HTTP request and all subsequent HTTP requests also failed but with HTTP 503 service unavailable error. From thereafter, none of the requests were successful. Also, only later some time, we realized that our application was not working because of this error and then we restarted Apache service. My questions are, in this kind of situation, how do I automatically restart Apache service when HTTP 503 error is encountered? Is there any Apache directive available to set? in general, what would cause a HTTP 503 error in Apache? NOTE: Mono helps in running applications developed in .NET on a Linux-based OS. EDIT: I agree on finding the root cause of this problem. In fact, we've been analyzing that too. Till we resolve it, am finding whether this could be restarted immediately on its own without having any downtime/service disruption for application users.

• How to create Windows Vista/Windows 7 Startup disk or Rescue disk or system restore points on a CD?

  - by goldenmean

  Hello, I have two laptops, one having Windows-Vista home premium and other one having Windows-7 professional. Both versions of OS are OEM installs(pre-installed when I bought the laptop) and I do not have the Windows Installation disks for them. usually the installation disks provide a repair option in case one needs to repair/rescue a improper windows installation. But since I dont have the installation disks, I want to create rescue disks/startup disks for these. My questions are : 1] How to create a system rescue disk/startup disk on a CD from these two versions of Windows? 2] Doesn't the system restore points which Vista/Windows-7 create, cannot be created on a CD disk instead of hard-disk? 3] If I have a manual backup of my windows registry, in which I have exported all the registry to a file and I have that file on a CD, how to restore that registry back to the windows installation which might not be booting up properly due to bad registry problem. EDIT: 4]Is there any way to use these system restore points directly during bootup of the laptop, if windows does cannot boot properly due to problem. First laptop is HP Pavillion dv6646 and second one is Sony VAIO VCPEE series. thank you. -AD

• How do I keep the keyword.url setting in firefox to default when you restart the browser without del

  - by user34801

  I am on the latest version of Firefox (not beta or anything like that) and currently my keyword.url is stuck on search.google.com (which I don't remember setting even though the about:config says it's a user setting. Can someone tell me how to set it back to default and keep it at default when I reset my browser? I do not want to delete prefs.js as I do not want to go thru setting up all the extension settings I have just to have my location bar search google (if this is the only way then I'll stick with searching from the search bar instead). I've checked all my extensions that may effect the location bar but could not find anything that says it would change the default search engine for this. I've also tried to open the prefs.js in wordpad or notepad but it just ends up freezing when trying to edit it at all (yes the browser is closed at the time). I also deleted the prefs-1.js (along with 2 others) that were older (after trying to rename those to prefs.js and see if this corrects it. It might have but had such old extension settings I went back to my latest prefs.js with this one issue instead of the issue of setting back up a ton of extensions. I can give any other info if needed, someone please help me fix this issue if possible.

• How to install Windows with no CD drive boot option in BIOS?

  - by Kris Hollenbeck

  I have a new computer which I built from scratch and I am trying to install a copy of Windows Vista on it. I am able to get to the BIOS and change the boot options which are as follows.. -Built-in EFI Shell -SATA: ST31000528AS I have searched around for and everything I find says to boot from the CD rom. However, as you can see. That is not an option for me. So I am wondering if there is another way around this? Is it possible to boot the Disk from the EFI Shell? Any help is much appreciated. Thanks EDIT: I have tried this.. http://technet.microsoft.com/en-us/library/dd744321%28v=ws.10%29.aspx UPDATE: I managed to make my USB bootable via the BIOS and I have copied my windows Vista disk onto my USB via drag and drop. However I am still not able to get the windows install to start. Also I have tried booting it from the EFI shell using the following command.. blk6: blk6:\> \EFI\BOOT\BOOTX64.EFI Still no luck..

• What is proper relationship between /etc/hosts and DNS A records for a Linux server?

  - by MountainX

  I have an Ubuntu server. It is going to be a web server with a URI of www.example.com. I have a DNS A record pointing www.example.com to the server's IP address. Let's say I pick "trinity" as the hostname for this server. I want to set up the DNS records correctly. I need reverse DNS to www.example.com, so a CNAME for www.example.com doesn't seem appropriate. Here's my question: Is it considered best practice to set up two DNS records (which in my case would likely be two A records), one for www.example.com and one for trinity.example.com, both pointing to this server's IP address? (Or, even if it is not accepted as a best practice, is it a good idea?) If so, would the following be a proper /etc/hosts file? $ cat /etc/hosts 127.0.1.1 trinity.local trinity 99.100.101.102 trinity.example.com trinity www.example.com This server is a Linode and Linode's docs seem to imply that the above approach is best (if I am reading them correctly). Here's the relevant section. I bolded the line that seems to apply here. Update /etc/hosts Next, edit your /etc/hosts file to resemble the following example, replacing "plato" with your chosen hostname, "example.com" with your system's domain name, and "12.34.56.78" with your system's IP address. As with the hostname, the domain name part of your FQDN does not necesarily need to have any relationship to websites or other services hosted on the server (although it may if you wish). As an example, you might host "www.something.com" on your server, but the system's FQDN might be "mars.somethingelse.com." File:/etc/hosts 127.0.0.1 localhost.localdomain localhost 12.34.56.78 plato.example.com plato The value you assign as your system's FQDN should have an "A" record in DNS pointing to your Linode's IP address. For more information on configuring DNS, please see our guide on configuring DNS with the Linode Manager.

• ProCurve ACL to prevent a subnet from leaving the switch

  - by kce

  I have a single HP ProCurve 2610 in a remote location that is connected in with the rest of the network via SHDSL. There are two Layer-3 networks on this segment. ACLs are setup to deny one subnet (192.0.2.0/24) from ever being able to leave the switch by virtue of being applied to port attached to the upstream connection. The other subnet should be permitted to freely leave the switch. Both subnets are on the same VLAN. Unfortunately SFlow very clearly show broadcast traffic from 192.0.2.0/24 on the upstream connection. ProCurve ACLs are not my strong suit but I feel like I'm missing something very simple here. ip access-list extended "Filter for Camera Network" deny ip 192.0.2.0 0.0.0.255 0.0.0.0 255.255.255.255 log permit ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255 exit interface 24 name "DSL - UPLINK" access-group "Filter for Camera Network" in exit Unless I am mistaken traffic from 192.0.2.0/24 should be dropped as it crosses the uplink port (int 24) whereas all other traffic will be permited by the following default allow rule. What exactly am I missing here? EDIT: Firstly, why do you have two subnets contained in the same VLAN? Because that's how it was configured by a previous administrator and while it makes conceptual sense that a single subnet is "mapped" to a single VLAN there's no technical constraint that I am aware of that makes this have to be the case. Instead of filtering inbound traffic on your uplink, you should be filtering outbound traffic. The HP2600 series can only filter inbound traffic on interfaces. Should I change my filter to deny any to 192.0.2.0/24?

• Blank list of windows services

  - by Joe

  Recently when I open windows services (always as administrator) I get a blank list of services: When I try and click on one of the empty lines I get this "Script Error" message: This happens over and over again, after several times I restarted my computer. I can't pinpoint exactly when this started happening or if I made any specific changes to my computer at that time. Someone told my to try running scf /scannow as administrator, but when I try to do that the scan stops at 34% and I get the message: "Windows Resource Protection could not perform the requested operation." I am running Windows 7 Enterprise 64 bit, and I would really like to avoid reinstalling windows. Does anyone know how to fix this? Edit - Here is another attempt I made and some more information that might help: Following WhoIsRich's suggestion, I tried the command sfc /scannow /offbootdir=c:\ /offwindir=c:\windows. This gave the error message "The arguments passed to sfc are invalid. The offline windows directory specified points to the online system", and then I realized this command is meant to be run after booting from another system. Since I don't have my windows installation disk right now, I used my own system to create a recovery disk, and then restarted my computer and used the recovery disk to boot. I then ran the above command, and I got the following message: "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log". I then restarted my computer and let it boot up normally. The problem with windows services persists, and the CBS.log file is a long log file with many entries, and I don't know if there is useful information in it, and if there is, how to find it.

• Windows: disable remote access of local drive, even by domain admin

  - by Matt

  We have a network of Windows 7 PCs that are managed as part of a domain. What we want is for the domain admin to be unable to view the PC's local drive (C:) unless he is physically at the PC. In other words, no remote desktop and no ability to use UNC. In other words, the domain admin should not be allowed to put \\user_pc\c$ in Windows Explorer and see all the files on that computer, unless he is physically present at the PC itself. Edit: to clarify some of the questions/comments that have come up. Yes, I am an admin---but a complete Windows novice. And yes, for the sake of this and my similar questions, it is fair to assume that I am working for someone who is paranoid. I understand the arguments about this being a "social problem versus a technical problem", and "you should be able to trust your admins", etc. But this is the situation in which I find myself. I'm basically new to Windows system administration, but am tasked with creating an environment that is secure by the company owner's definition---and this definition is clearly very different from what most people expect. In short, I understand that this is an unusual request. But I'm hoping there is enough expertise in the ServerFault community to point me in the right direction.

• Is it possible to add/register an MIB for the Windows built-in SNMP service?

  - by michielvoo

  I need to build monitoring into an existing .NET application. I will use SNMP to send the application's status to the Windows SNMP service. I have used a .NET library to create the SNMP SET request according to the MIB that I have been provided with, and with the correct community. My code now sends multiple 'variables' in a SET request, for example: Id: ".1.3.6.1.4.1.43607.1.1.1.1.1" (ObjectIdentifier) Data: 42 (Integer32) On my machine I have enabled the SNMP service, configured a community with READ/WRITE permissions, and added localhost to the list of hosts to accept requests from. When I send the SET request I get a response, but it has error status 17 which, according to MSDN means SNMP_ERRORSTATUS_NOTWRITABLE. The response also has error index set to 8, which is the number of variables I send. If I send 7 variables, the error index is set to 7. I think the problem is that the Windows SNMP service is preconfigured to only accept SET requests for a fixed set of MIBs. How can I get the Windows SNMP service to 'accept' my custom MIB SET request? Edit: I downloaded and installed the Windows Server 2003 Resource Kit and tried to 'compile' the MIB file with mibcc.exe ("SNMP MIB Compiler") but I have not been able to compile any MIB files (even the most basic ones like SNMPv2-SMI.mib).

• Host Primary Domain from a subfolder

  - by TandemAdam

  I am having a problem making a sub directory act as the public_html for my main domain, and getting a solution that works with that domains sub directories too. My hosting allows me to host multiple sites, which are all working great. I have set up a subfolder under my ~/public_html/ directory called /domains/, where I create a folder for each separate website. e.g. public_html domains websiteone websitetwo websitethree ... This keeps my sites nice and tidy. The only issue was getting my "main domain" to fit into this system. It seems my main domain, is somehow tied to my account (or to Apache, or something), so I can't change the "document root" of this domain. I can define the document roots for any other domains ("Addon Domains") that I add in cPanel no problem. But the main domain is different. I was told to edit the .htaccess file, to redirect the main domain to a subdirectory. This seemed to work great, and my site works fine on it's home/index page. The problem I'm having is that if I try to navigate my browser to say the images folder (just for example) of my main site, like this: www.yourmaindomain.com/images/ then it seems to ignore the redirect and shows the entire server directory in the url, like this: www.yourmaindomain.com/domains/yourmaindomain/images/ It still actually shows the correct "Index of /images" page, and show the list of all my images. Here is an example of my .htaccess file that I am using: RewriteEngine on RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteCond %{REQUEST_URI} !^/domains/yourmaindomain/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /domains/yourmaindomain/$1 RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ RewriteRule ^(/)?$ domains/yourmaindomain/index.html [L] Does this htaccess file look correct? I just need to make it so my main domain behaves like an addon domain, and it's subdirectories adhere to the redirect rules.

• Building a computer for the first time from scratch - will this really work?

  - by Nike

  Hey there. I'm building my own computer, and i just finished picking out all of my parts. Now i just want to be sure it'll all work before i order it. I'm mean specifically if the RAM & Graphic card will fit on the motherboard i chose. Below is a list of all parts. I'm sorry, i selected the parts from a Swedish website so it might be hard to understand some parts. Google Translate will help ;) I really appreciate any help/suggestions. Thanks in advance! :) Oh, and here's the parts i mentioned: EDIT: As i'm not allowed to post more than one link here, i'll just link to my homepage: http://nike1.se/c/ I know i didn't choose the most expensive parts, but this won't be my primary computer. I'm only going to use this one for testing purpose, if that makes any sense. I'm sorry for my english, i'm just so tired now. Haha! Once again, thanks in advance! :)

• Is Cloud Print to blame for my inability to print?

  - by VarLogRant

  I have just moved to the Chrome beta (first 9.something and currently 10.0.648.127) on my Windows 7 64-bit machine, and my good web browsers (Firefox Beta and Chrome) can no longer print, and neither can Komodo Edit. The problem seems to have started when I tried to enable Google Cloud Print. Frustratingly, I can still print from IE 9 RC, and also from other machines in the office, which means the problem is entirely on this Windows machine. When I try to print from Chrome, first time I get the printer dialog, and once I click print, it waits, then pops up "Something went wrong", and each time after, it pops up with "No Printer Found". Under Firefox, I get "An unknown error occurred while printing", as does Komodo. I have printed from these applications before, and have even printed from Google Cloud Print. Once. But then it stopped. I really don't know where to go next in debugging this thing, and the Google results I see tend to be from 2007. I'm not ready for the paperless office yet, so please help!

• Is VGA port hot-pluggable?

  - by Martin Bøgelund

  In meetings, I often see people detaching the VGA connector from one running laptop and connecting it to another, while the projector is still on. Is this 100% risk free, and OK by design of the VGA standard? If there's a risk involved in hot-plugging VGA, can it be removed by turning off or suspending either laptop, display, or both? I see this being done all the time without causing disaster, so clearly I'm not interested in answers stating "we do it all the time, so it should be OK!". I want to know if there's a risk - real or in theory - that something breaks when doing this. EDIT: I did an internet search on the topic, and I never found a clear statement as to why it is safe or unsafe to hot swap VGA devices. The typical form is a forum question asking basically the same question as I did, and the following types of statements Yes it's hot swappable! I do it all the time! It involves some kind of risk, so don't do it! You're some kind of moron if you think there's a risk, so just do it! But no explanation as to why it safe or not... Joe Taylors answer below contains a link to a forum post and answers that basically give me the same statements as mentioned above. But again, no good explanation why. So I looked for an actual manual for a projector, and found "Lenovo C500 Projector User’s Guide". It states on page 3-1: Connecting devices Computers and video devices can be connected to the projector at the same time. Check the user’s manual of the connecting device to confirm that it has the appropriate output connector. [image] Attention: As a safety precaution, disconnect all power to the projector and devices before making connections. But again, no good explanation.

• How can I control which sound card Ubuntu uses for playback?

  - by GorillaSandwich

  I am dual-booting Ubuntu 9.04 and Windows XP but am new to Ubuntu. In Windows, I use an M-Audio Audiophile 2496 sound card for recording (because it has RCA input jacks for my mixer), but I don't use it for playback (because my speakers use a 1/8 inch jack); instead, I use the motherboard's built-in sound card. I tried to recreate this arrangement in Ubuntu, but despite selecting the built-in card for all playback under System > Preferences > Sound, I still have inconsistent results. Rhythmbox plays back through the integrated card, but Flash content in the browser and games in the OS send their audio to the Audiophile card. I have seen recommendations to use a program called "Jack" to control this, but I installed it and found it baffling. How can I control which card is used for playback, other than disabling one card (as I discovered how to do and explain below)? Also, is there a GUI for disabling hardware, or is it necessary to edit a configuration file?

• How to interrupt software raid resync?

  - by Adam5

  I want to interrupt a running resync operation on a debian squeeze software raid. (This is the regular scheduled compare resync. The raid array is still clean in such a case. Do not confuse this with a rebuild after a disk failed and was replaced.) How to stop this scheduled resync operation while it is running? Another raid array is "resync pending", because they all get checked on the same day (sunday night) one after another. I want a complete stop of this sunday night resyncing. [Edit: sudo kill -9 1010 doesn't stop it, 1010 is the PID of the md2_resync process] I would also like to know how I can control the intervals between resyncs and the remainig time till the next one. [Edit2: What I did now was to make the resync go very slow, so it does not disturb anymore: sudo sysctl -w dev.raid.speed_limit_max=1000 taken from http://www.cyberciti.biz/tips/linux-raid-increase-resync-rebuild-speed.html During the night I will set it back to a high value, so the resync can terminate. This workaround is fine for most situations, nonetheless it would be interesting to know if what I asked is possible. For example it does not seem to be possible to grow an array, while it is resyncing or resyncing "pending"]

• Replacing compiz/metacity with openbox reduces workspaces to 1

  - by Brian

  I like to use the GNOME desktop, but I prefer to replace its window manager with openbox, with 4 workspaces. However, when I run openbox --replace, the number of workspaces available drops to 1. If I go into obconf, workspaces is still configured to be 4 (~/.config/openbox/rc.xml shows the same). I can get the workspaces to reappear by changing the value in obconf to anything else, and then back to 4. I have just been dealing with this problem since Ubuntu 9.04 (now up to 10.10) since I don't reboot very often. But it's really annoying to have to reset my workspaces whenever I do have to reboot. Changing the value in rc.xml and running openbox --reconfigure does not seem to have any effect. So what is obconf doing that I'm not (sends a dbus message perhaps [EDIT: watching with dbus-monitor I see no messages when changing the workspaces value in obconf])? I was hoping there would be a cleaner way to change the window manager than just running openbox --replace at login. So my questions are: Is there a better way to specify an alternate window manager (i.e. a way that doesn't cause the workspaces to break)? If not, how can I automatically set the number of workspaces back to 4? Update: I finally got around to trying what I commented on MrShunz's answer (adding WINDOW_MANAGER=/usr/bin/openbox to ~/.gnomerc). But the effect is the same as openbox --replace.

• Does IIS Sometimes Allocate More Worker Processes Than Configured?

  - by Paul Williams

  We have an IIS 7.5 web service on Windows Server 2008 that handles WCF requests from C# clients. This service is configured to have Maximum Worker Processes = 1, so it is not a web garden. IIS is setup to recycle itself at the same time every day (3 AM). I am trying to debug gnarly connection issues, so I wanted to be sure the application pool was not recycling itself. I configured the pool to log an event when it recycles itself. To my surprise, I see the following entries in the System event log: Level: Information Date/Time: 3/23/2012 3:00:00 AM - Source: WAS - Event ID: 5076 A worker process with process id of '6636' serving application pool 'MyAppPool' has requested a recycle because it reached its scheduled recycle time. Level: Information Date/Time: 3/23/2012 2:59:39 AM - Source: WAS - Event ID: 5076 A worker process with process id of '9364' serving application pool 'MyAppPool' has requested a recycle because it reached its scheduled recycle time. IIS is correctly recycling the application pool at 3 AM. However, I do not understand why I would be getting two recycle events in the log within a few seconds of each other. The maximum number of processes is 1. Does IIS sometimes allocate multiple processes for an application pool that is specified as having 1 process? -- edit -- I connected at about 4 PM today and only saw 1 w3wp.exe process. There are no other event log entries that would indicate a crash.

• limiting connections from tomcat to IIS - proxy? iptables?

  - by Chris Phillips

  Howdy, I've webapp on tomcat6 which is connecting to an M$ PlayReady DRM instance on IIS6.0 The performance is seen to be best when we bench mark (using ab) the DRM service with 25 concurrent connections, which gives about 250 requests per second, which is ace. higher concurrent connections results in TCP/IP timeouts and other lower level mess. But there is no way to control how the tomcat app connects to the service - it's not internally managing a pool of connections etc, they are all isolated http connections to the server. Ideally I'd like a situation where we can have 25 http 1.1 connections being kept alive permanently from tomcat and requesting the licenses through this static pool of connections, which I think would the best performance. But this is not in the code, so was looking for a way to possibly simulate this at the Linux level. I was possibly thinking that iptables connlimit might be able to gracefully handle these connections, but whilst it could limit, it'd probably still annoy the app. What about a proxy? nginx (or possibly squid) seems potentially appealing to run on the tomcat server and hit on localhost as we might want to add additional DRM servers to use under load balance anyway. Could this take 100 incoming connections from tomcat, accept them all and proxy over the the IIS server in a more respectful manner? Any other angles? EDIT - looking over mod_proxy for apache, which we are already using for conventional use on an apache instance in front of this tomcat instance, might be ideal. I can set a max value on the proxy_pass to only allow 25 connections, and keep them alive permanently. Is that my answer? Many thanks, Chris

• How do I identify Blackberry / OWA users in my IIS logs?

  - by Quinten

  We just rolled out a Blackberry Express Server, and would like to make sure that all Blackberry devices that our users own are connecting SOLELY through the BES server. We are running Exchange 2010 SP1. I've read some links that discuss blocking BIS at the firewall level. Before doing that, however, I'd like to individually contact all users with Blackberries and make sure that they have a chance to switch to the BES server. I've sent a company-wide email, but unsurprisingly folks tend to tune these out until they are forced into action. Is there an easy way to identify the users with Blackberries by searching IIS logs, or perhaps using the Exchange Management Shell? Especially some automated way? I've tried searching for the Blackberry identifier, but it does not appear next to any user name, so it's not as helpful as it could be. Edit: to clarify, what I'm talking about is the fact that Blackberries can use OWA to download mail to the phone. We do not allow IMAP or POP access through our firewall so that's not a concern--just folks with Blackberries using Blackberry's hack to allow it to connect to Exchange without a BES server. As far as I know, Blackberries are the only popular phones that use this method to download mail.

• Password Authentication Fails - NTLMv2

  - by JMeterX

  Environment: Windows 2000 sp4 EDIT: Domain Controller with no trust setup with the Win2008 Server Windows XP machines Windows 2008 Server Netapp NAS Problem: We have a shared folder that resides on a NAS using a Windows 2008 AD for the authentication with the proper permissions setup. When the Windows 2000 machine tries to open the share residing on the Win2008 machine, it is prompted for a username and password. Upon entering the credentials it continuously re-asks for credentials. Important Details: The Windows 2000 machine can ping both the XP machines and the Windows 2008 Server The Windows 2008 machine is mandated to only use NTLMv2 The Windows 2000 machine was originally set to NTLM but was recently switched to NTLMv2 if negotiated for the purpose of trying to connect to the share. As I am sure it will come up, we are using Windows 2000 because of contractual obligations Questions: Why is password Authentication failing in this case? After setting a GPO for the Win2000 machine for it to use NTLMv2, do we need to reboot the machine for the changes to take affect? We used SECEDIT to update the GPOs without rebooting. UPDATE We checked both of the 2008 Domain Controllers to find an error code. We received: Microsoft_Auth_Package_V1_0 0xc000006a Event ID: 4776 I know this to be an authentication error via THIS article "The value provided as the current password is not correct" We know this password to be correct, but since these two domains (Win2000 & Win2008) do not have a trust setup what authentication account needs to be used? One that resides on the Win2000 hosted domain?
