[Samba] Mapping Problem

[COUNTERMAN, DANIEL (CONTRACTOR)]

All,

	The Windows 2000 client is on my side of the firewall (the error message is: "remote computer is not available"), the Windows XP client is on the other side of the firewall, (the error message is: "The specified network name is no longer available").  I am able to ping both the IP address and server name of the CIFS/Samba server.  I cannot perform the mapping, via Map Drive, then I connect as different user name and I enter a user id that I setup with smbpasswd (testcifs).  Then I receive both these messages, I have searched message lists and the web for documentation on these errors, and I am unable to find anything that works.  I seen a document that said if you could ping, then the next thing was to setup lmhosts on the client, which I did, that still does not work, so there may be some configuration problem of some sort.

I appreciate your help very much.
