I have a user (Windows XP Pro, SP3) who is periodically having trouble accessing file shares on our Windows 2008 R2 server. One minute he'll be able to open them all just fine only to find that when he tries again later, he can open all but maybe 1 share. The error he gets is the one that's like "\\fileshare is not accessible. You may not have permissions to access this folder. Please check your permissions or contact your systems administrator...."
I've checked his permissions and he has full permissions to access all shares. The weird thing is that this issue only happens half the time. One thing: the user is leaving the office and working from home, accessing the shares via VPN connection. Again, same problem; half the time he'll be able to open all the shares just fine through VPN, while the other half the time he'll be able to open all but 1. That 1 changes for no apparent reason. Sometimes it's shared folder A, sometimes it's shared folder B....no rhyme or reason to it.
I've checked his event logs and the only error I see at the time he last tried to access a share and was unsuccessful was this one:
Error 4/18/2011 9:12:00 AM Dhcp None 1002 N/A D9CGJTF1
Does anyone know what could be up?
