We're running a Win 2k3 R2 Standard 64-bit edition server. On this server we're running a fileserver and the ability to allow remote login to our network through vpn. We do not currently utilize a domain setup, all user accounts are local accounts on the server.
Each employee is given a unique account to login to the server. The password is a randomly generated 16 character long string, which makes it hard to remember. What we've done is basicly had the password stored on the client machine (standard "Remember Me" functionality). This has worked well.
However, last night our server automatically restarted after an automatic update. After that, some of our employees, myself included, had to re-authenticate with the server, submitting our credentials again. Then again, some others did not have to re-authenticate. Do you guys have any idea why this is? Is there a setting to prevent this?
I've checked the logs but I couldn't find anything of interest. Then again I'm not really sure what I'm looking for.
Thanks in advance, I'll try to answer any additional questions you may have.
Edit: When I say "login" or "authenticate" I mean through the standard windows samba protocol.
Edit 2: Ok, new day. Tonight the server restarted again, and the same two clients that had to re-authenticate yesterday had to re-authenticate today as well. The rest did not.
