Recently In installed Windows NT Server 4.0 on my PC which is not connected to network. but i found the NTLMSSP service not installed. Due to that a lot of things including IIS is not working. Please let me know how can I install the service

Did you ever get this fixed? I'm experiencing the same problem.

Just install the RPC-Configurator (in case you are runnig on NT4). Best regards.

On Windows NT: NtLmSsp is installed with the "RPC Configuration" service. To install the NtLmSsp service, do the following: a. Go to Control Panel-->Network-->Services. b. Click Add, and then select it to be added. On Windows 2000: NtLmSsp is installed with the "Client for Microsoft Networks". To install the NtLmSsp service, do the following: a. Right-click on "My Network Places", and select Properties. b. Right-click on "Local Area Connection", and select Properties. c. Click Install. d. Select "Client", and then click Add. e. Select "Client for Microsoft Networks". f. Click OK. If you do not have any other networking components installed, you will get the following message: "You must install and enable at least one protocol for this connection to work. Do you want to select a protocol now?". Note that a protocol is NOT needed for the PGPsdk Service to work correctly. If you are installing "Client for Microsoft Networks" only for PGP, you can disable the service by deselecting the check box next to it in the Components list.
