Strange Windows login problems

[tealmaroon]

Hi,

I'm running XP Pro in order to host a temporary website using IIS and MSSQL however,
after 10 minutes it's not possible to connect to my tables (using SQL Manager) using
the trusted option, I can login using one of the SQL logins created by myself.

Additionally, when Windows 'timesout' to the login screen after so much inactivity,
the account is prompted for a password when one isn't (yet) set onto that account - which
would suggest to me that something is causing the Windows 'login system' to fail, prehaps
a known issue or a virus, i've done a boot time scan with Avast! anti-virus but no such luck.

I've also attemped to reformat the PC and reinstall the required software, it only replicates
the above fault.

Many thanks!

Control Panel->Power option->Might consider turning off the option to require password when doing into standby.

Hi again,

I can't see such option, also - this happens even when I don't timeout. Say i'm working with MSSQL, i will suddernly get the 'cannot Generate SSPI context' error message, if I press [WIN] + L (logoff/switch), there is a password field. I've tried setting a password of my own but it rejects the login attempt.

I've scanned with HiJackThis tonight, but nothing seems to be out of the ordinary.
