Microsoft Network

[George]

I had a 5 station MS Network running, all XP Pro. I
replaced one of the older PC with a new one, set it up to
network, and now I have one computer on the NW that I
cannot see when I bring up the local area network but
when I bring up the Workgroup it is there. I cannot
access it because it gives the error "I might not have
permission to use this resource." None of the other 4
computers can access this computer but it can access all
of them. I had some shared files that I had to move to
another computer for sharing.
I also have run into the problem of trying to open
encrypted email on the same computer. Could it be
related?
I suspect a naming convention error, but cannot find it.
I have checked everything 10 times but to no avail.

George,

On any XP Pro computer, check to see if Simple File Sharing (Control Panel -
Folder Options - View - Advanced settings) is enabled or disabled. With XP Pro,
you need to have the SFS settings properly set on each computer.

With XP Pro, if SFS is disabled, check the Local Security Policy (Control Panel
- Administrative Tools). Under Local Policies - Security Options, look at
"Network access: Sharing and security model", and ensure it's set to "Classic -
local users authenticate as themselves".

With XP Pro, if you set the Local Security Policy to "Guest only", make sure
that the Guest account is enabled, thru Local User Manager (Start - Run -
"lusrmgr.msc"), and has an identical, non-blank, password on all computers. If
"Classic", setup and use a common non-Guest account, with identical, non-blank,
password on all computers.

For XP Pro with Simple File Sharing enabled, make sure that the Guest account is
enabled, thru Local User Manager (Start - Run - "lusrmgr.msc"), on each
computer.

Do any of the computers have a software firewall (ICF or third party)? If so,
you need to configure them for file sharing, by opening ports TCP 139, 445 and
UDP 137, 138, 445, and / or by identifying the other computers as present in the
Local (Trusted) zone. Firewall configurations are a very common cause of
(network) browser, and file sharing, problems.
