I am having a problem I just can't seem to resolve no matter what I try.  I
am trying to share 2 folders from one xp machine to another.  They are both
in the same workgroup and connected on same subnet etc.  When I try "net use
s: \\server\share" sometimes it works and sometimes it doesn't.  When it
doesn't work I get a username and password error and it asks for the password
for client\guest.

Things I've tried:

1) playing with local group policy (changed from guest to classic amongst
other things)

2) turned on simple file sharing

3) added the user on the client machine onto the server with same password
and added gave them permissions to the share and to ntfs

4) added EVERYONE user with full permissions to both the share and ntfs

5) turned off windows firewall

6) uninstalled security suites completely on both

7) net use s: \\server\share /user:server\serveruser serveruserpassword

8) created identical users with identical passwords on both machines and
added permissions accordingly

9) kicked server hard

I was sure I had it solved after I completely uninstalled avast security
suite (it was only disabled before) and I rebooted both machines and the
shares both mapped fine from a bat file.  It only worked until the next day.

I've never had problems like this before and I just can't seem to work it
out.  There is only 2 machines on this network so I can't work out with which
machine the problem lies.

Hopefully some genius out there can shed some light on this for me.

Thanks in advance
