Re: Vista adds computername\ to username

Mike,

I have a feeling this is going to be a common problem. I hope for others
that MS gets it into the KB. Thanks for sharing it. The LAN security change
completely solved my problem.

The fix described in this previous post won't work with Vista Home Edition. I'm trying to access my work network through a VPN and once I get through the Sonicwall to the network login Vista insists on prepending my computer name to my login user name which, of course, the network does not recognize.

I've tried the registry fix to the lmcompatibilitylevel key by setting it to 1 and that hasn't helped either. Is there someplace else I should be looking? Any hints as to how I can fix the problem?

i had this problem with vista home premium on both computers in the network. First, I was denied permission to access. I added a password protected user to the host computer. Then I turned on all file sharing permissions in host's network and sharing center. I added a password to the "guest" computer's user log-on. I think it was at this point that I could get to a log-on, and it gave me that prefix "computer name/user name" problem. I then went to the guest computer's network and sharing center, and turned sharing on for the public folder. After that, I was able to log on to the host computer. I don't know why, that's what happened.
