You can't log into that machine or any machine on the network?

To resolve this issue, increase the value of the IRPStackSize registry entry. To do this, follow these steps:1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:

 If the IRPStackSize entry is not present in this subkey, follow these steps:a. Click Edit, point to New, and then click DWORD Value.
b. Type IRPStackSize, and then press ENTER.

Note Type IRPStackSize exactly as it appears. The value name is case sensitive.

3. Click IRPStackSize, click Edit, and then click Modify.
4. In the Data Value box, type a larger value, and then click OK.

Note Values may range from 0x1 to 0xC. These values are equivalent to 1 to 12 in decimal notation.
If the problem persists after you complete the previous procedure, increase the value of IRPStackSize more.

I can log into any machine except this on one windows server 2003 which I demoted as member server as I was promoting other windows server 2008 as DC

Can you remote into the registry on that server and try the above steps?

It's for older versions of NT but it's worth a shot.

Try logging in to the server locally using the admin account. From there check your drive space.

how can I remote in the registry
Scott CSenior EngineerCommented:
1.Run REGEDIT on your workstation or on another Server.
2.Click on File, then choose “Connect Network Registry”.
3. In the Select Computer search box either browse Active Directory to locate the remote server, or type its name in the dialog box.

See if that will work.  

Do you know if there is enough disk space as Will suggested?
