Virtualized server rejoining domain

I have a legacy Windows 2000 SP4 box that needed to be virtualized into a VMware Server guest. I ran VMware converter with no problems, turned off the old host, gave the guest the same IP number as the old host, and brought it up on the network. The actual conversion happened a few months back (and I just copied recent data back to it.)

I was not able to log in to the domain (Windows 2003 ADS) and a search revealed that since the conversion was over 30 days old, I must re-join the domain. I made the guest a workgroup member, rebooted, deleted the orphaned computer account in Users and Computer Manager, and then rejoined the domain without any problem. (This is also a secondary DNS server and transfers are OK.) The computer shows up in Domain User and Computer manager.
Login to the domain is fine now. However, the guest computer does not show up when browsing networks and computer browser is on. Additionally, trying to find shares on the guest does not work. Mapping a drive to guest shares does not work. Mapping drives FROM the guest to other domain shares is fine.

I can ping the name properly.

There are no errors in the event logs indicating there is a problem.

ANY ideas?

Oh, and I re-added all the domain permissions back in to the guest file system and shares. No problem there.
Any Aniti Virus installed?  Maybe port blocking?  If so find the setting in the AV software to allow the current network.

Windows firewall is off. I can uninstall Symantec AV....though it was on there before and has no port blocking. I suspect something with a SID, but I have no errors in the logs.

I'm now trying to go back to square one and use a copy of the original VM image, deleted the computer account in AD and am re-joining.

Ugh. I have a million errors in the log now.
SIDs are definitely off. Exchange will not start on the guest.

Any way to get back the original SID without booting into AD restore mode? I'm 5000 miles away.
If you have many users and a large AD you may want to wait a while before re-joining domain as it may take a while for the computer account to get deleted from all servers.

You have Exchange installed on this machine?  Is it also a DC?

Can you provide a few of the errors, the first ones are the best.

This machine is NOT a DC.
It IS an exchange server.
We have only 15 user accounts and there is a second server acting as only a DC/GC for AD "backup" on the local net.

I will get back with errors. It is obvious Exchange cannot start because the computer account is incorrect. I am looking at how to correct this. re. http://support.microsoft.com/kb/297295 "Missing exchange computer account."

Delete AD computer account again. Rejoined Guest server OK.
Taking a while to log in. I will check DNS. It is currently pointed to itself for resolution and it is a secondary DNS server from the master (the main AD server.)
It did a master transfer, but I'll double check anyway.

OK. Back to where I started. New computer account. Re-added Exchange object where they should be so it starts. No errors in the log.
STILL can't "net use \\IWPW2000\c$" from the other server. (Error: The network name cannot be found.)
Can't see the computer when browsing Network neighborhood from the other server.
Network Neighborhood is empty on the guest server.

Lost.

DNS is correct and can transfer from the master. nslookup succeeds in requests.

"Net view" from the host does not show my guest server named IWPW2000

Author

Commented:
Net view from the guest reveals nothing at all. Pings OK. DNS resolution OK. WINS resolution OK. File permissions OK.
Aaaarg!
Fixed. SO SIMPLE!
Under properties of the network connection, I checked the boxes to enable File and Printer sharing and Client for Microsoft Networks.

Originally I set the guest as "Host only" networking and I assume it disabled these.

Four hours of my life I will never get back for two check boxes.... welcome to IT....
