Hello,
I have a problem with one of my users not being able to use any network resources when connected to our Office via PPTP VPN. We use TMG 2010 for firewall and also for VPN connections.
This is the problem. When user connects to the VPN it authenticates him and connection is established. After that he cannot access his Workstation over RDP and he cannot access his share on network. After doing a quick search in the event logs on TMG i found this in the security log:
An account failed to log on.
Subject:
Security ID: NETWORK SERVICE
Account Name: TMGSERVER$
Account Domain: OURDOMAIN
Logon ID: 0x3e4
Logon Type: 3

Network Information:

Transited Services: -
Package Name (NTLM only): -

The thing is, that the affected user can logon to his Workstation with no problems which eliminates the possibility of locked-out account, incorrect username or bad password. I've also changed the users password but that didn't change a thing. I also created an exact copy of the affected user. VPN Works just fine with this newly created user.
I'm a bit blind here so any help would be much appriciated.
Best regards
