NT domain down. Why can workstation can still login?

Here's the deal.

I have 3 servers:

W2K application server
NT application server
Novell 5 file and print server.  

I was planning to phasing out the NT server (it runs a small application) and eventually moving to AD.  All the workstations use Novell client as their primary login client and they also login to the NT domain.  The w2k server is a standalone in it's own workgroup.  Yesterday the NT server failed bad.  I believe the new power supply I put in was faulty and it fried the SCSI backplane.  It cannot recognize any drives.  No biggie since I was going to phase it out anyway.  My question is my client stations are still able to login without any problems.  They still thinks the NT domain is up.  I assume the info is cached somewhere.  

Will this situation last forever until I upgrade to AD?  And as far as I know there is no way to make a w2K server emulate a NT domain?  Is this correct?

I may have to temporary join the client to a workgroup that the w2k server resides in.  However when I do that the clients will need a local profile on their own machine.  I don’t want to recreate everything on their workstations.  Is there a way to convert their domain profile to a local profile?  Can I just create a local profile and copy all the data from their domain profile directory?

Thanks for your help in advance.

in NT, 2k or XP, logins are cached.

System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Value Name: CachedLogonsCount
Data Type: REG_SZ (String Value)
Value Data: 0 - 50 (0 = disabled, 10 = default)

If or when the domain goes down, a user will still be able to login up to the specified amount of times in the registry.
If you clients can authenitcate then you have a BDC somewhere that just got promoted to PDC when you NT server failed (possibily your W2K server), just to be save, can you print to a network printer?

After the threshold is reached I assume the stations will no longer be able to login.  If this value is disabled does that mean they can login indefinably or as I assume not at all.

No I don't have a BDC
like shad0 alluded to, if there is another controller on the network then they will be able to log on indefinitely. If the value is disabled, no client will be able to log on if there is no DC available for authentication.

So since I will not create my domain again.  I have to have my clients logon to a workgroup until I migrate to AD.  My question is when I create their local account can I  point the profile path to the directory that contained the domain account data?  I don't want to recreate their desktop environment?

Once you create the local account, just copy the domain profile to the local profile so their desktop settings are the same.
