EXPLORER.EXE corrupted or infected

Here's how to fix this issue:

1. CTRL-Alt-Del to bring up Task Manager.
2. Click File | New Task(run).
3. Type regedit in the Run box and click OK.
4. Browse to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution.options

5. Under this key there will be subkeys named explorer.exe and iexplorer.exe. Delete the explorer and iexplorer keys entirely. They should not be listed under the Image File Execution.Options key.
6. Close the Registry Editor.
7. Restart the computer.

Assuming no other viruses / adware / spyware / malware are interfering, the Windows desktop should load fine now

No more connections can be made to this remote computer/too many connection windows 2003 server

Currently I see 10 connections to the server.  If the 11th users tries to access the remote share on this server they receive the following message:

"No more connections can be made to this remote computer at this because there are already as many connection as the computer can accept."

how do you increase this from 10?  I thought Window server 2003 has suppose to support up to 65000 connections?

I have tried increasing the Max limit as suggested here:

2. Locate and then click to select the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\

CurrentControlSet\Services\Lanmanserver\Parameters
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type MaxMpxCt, and then press ENTER.
5. Right-click MaxMpxCt, and then click Modify.
6. In the Value data box, type the desired value, and then click OK.

with no change.
