Re: One user cannot access Server Shares/connect to Exchange server

There was a typo in the original message..
DNS in DHCP scope is pointing to SBS, NOT the ISP DNS. So we have no
issue there.

Hi,
I am hoping one of the experts on here can point me to the right
solution.
We have SBS and 10 users. Roaming profiles on the server. DHCP, DNS all
on SBS
DNS in DHCP scope is pointing to the SBS, on ISP DNS. I can safely rule
out DNS as the problem
One user can log into her workstation, but can only login after a long
while because windows cannot find the roaming profile and is trying to
login with a local copy.
It looks like somehow her account will not authenticate to the DC to
access shares & exchange.
We tried logging into another workstation with the same user account.
Same behavior. Same errors. However other users can login and check
their email and access network shares with out a problem. This makes me
conclude that there is something about her account that is messing
things up. I did not change anything on her account in AD. I disabled
trendmicro services on the workstation and that did not change a thing.
She can use webmail to check her email? That works fine. I am stomped.
Please help.
Here are all the logs related to this.

causes of this error include network problems or insufficient security
