I have two computers getting that pesky "Unable to open default mail folder"
error after an installation of ISA 2000 on an SBS 2000 box.
There were a lot of pre-existing errors on the network (this is a new client
we've taken on for the sole purpose of reconfiguring their SBS box and get it
working correctly) which I can not account for. To make matters worse,
another one of our techs was out there to do the ISA install when this issue
started so I have only a patchy account of details leading up to the problem.

Here's what I do know:
Email for two users worked fine until the ISA upgrade. After the isa
firewall client was applied to the client PCs these two users suddenly
started getting the above error.

Their email accounts were deleted on their respected PCs and recreated
several times. When that failed Their exchange profile was added to another
PC only to get the same error. On the same PCs other users (namely the
default account and the administrator) can get their emails.

It appears to me that as the issue follows them from computer to computer
that it is with their network account not their local computer settings.
I checked Exchange System Manager and there are no user logons corresponding
to their accounts in the users heading under their server. Another user,
Kathy, also has no login listed there but her email is working fine just the
same.

Can any one think of anything else?

Out of desperation I tried recreating their local profiles that didn't help.
I changed the order of their bindings per a KB listed in a previous posting
on this issue to not include ncacn_np (KB244523). I replaced the Secur32.dll
with a clean copy as per another KB whose number I do not have handy.

Always the same result: you do not have permissions to log on.

Do i have a bad SID or something? I can't find any relevant info in the
event logs and I'm out of ideas.

Thanks.
