I have a client with a small lan, running windows 2003 server with AD...
The MD has a Sony laptop that connects to the network via a built in 802.11b Network Card... eveything works perfectly when connected to the network.
When the laptop is removed from the network (the user takes it home / turn off the WiFi AP) you can no longer log into the domain, if you try it gives the following error message :
"The system cannot log you on now because the domain <DOMAIN_NAME> is not available"
Having the user log into a local profile is not an option as he needs access to the files stored in the network user profile.
I know this should work (my personal laptop Caches my credentials and allows me to log on when not in the office, and so does every other laptop I have ever seen)...
I have tried changing the following Reg key, but it has made no difference :
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\Winlogon\
Data Type: REG_SZ
Values: 0 - 50 (now set at 50)
I have also installed SP2, still no difference.. I have also removed the laptop from the domain (made up a fake workgroup then joined the domain again)...still no difference...
I have also reset the passwords for all the accounts that use this computer... still no change...
I have also checked the domain policy on the server and the above Reg Key is also set to 50... still no change...
ANYONE... PLEASE... this is doing my head in!
