trouble accessing DC

[Guest]

Windows 2000 Active Directory domain running in native mode. A forest with
a single domain. All DC are fully patched.

I am unable to access the shared folders (sysvol, etc) of domain controller
SV52 from any computer in the domain.

--- The machine is pingable by name and IP.
--- DNS looks good. (forward and reverse)
--- WINS records are good.
--- SV52, does not show in Network Places from other domain computers
--- SV52, does show in Network Places from itself
--- SV52 is not accessible over the network at all, //SV52 does not work
--- SV52 is accessible using //SV52 when logged into itself

I'm thinking the machine account is corrupted in some way, but I'm not sure
yet.

The dcdiag command /test:machineaccount gives the following return.

I'm leaning towards using dcpromo to demote the machine, removing it from
the domain, re-adding it to the domain, and then using dcpromo to promote it.

Any ideas would be appreiciated.

Seems like demote, reinstall, promote is the easiest solution in this case.

Some things to do if you want to spend some time to troubleshooting the
current install.
Check that NetBIOS over TCP/IP is enabled.
Use nltest /DSQUERYDNS (Nltest is a part of the Windows Server Support Tools
found at your Windows Server CD.)
Verify that DNS is configured correct.
