How to Disable Chat in Windows NT

Article ID: Q102419

= SUMMARY =

In Windows NT, it is possible to prevent other users on the network from sending your machine Chat messages by changing entries in the Registry Database using REGEDT32.EXE.

WARNING: Registration Information Editor (REGEDT32.EXE) is a very powerful utility that allows you to directly change the Registry Database. Using Registration Information Editor incorrectly can cause serious problems, including hard disk corruption. It may be necessary to reinstall the software to correct any problems. Microsoft does not support changes made with Registration Information Editor. Use this tool at your own risk.

= MORE INFORMATION =

To disable Chat for a user in Windows NT, change the following key value to zero (0):

HKEY_CURRENT_USERTrusted Shares$

This prevents Chat from loading on your machine when another user tries to send your machine a Chat message.

The computer attempting to send the message receives the following message:

 did not respond.

This setting is only for the current user of the machine. Each user on the machine who wants to disable Chat must change the Registry entry.
