SYMPTOMS
When the SMS site server and the remotely controlled computer are using separate primary WINS servers, the SMS Administrator cannot locate the client for remote control using TCP/IP (until the WINS database is replicated to its partner). Once the WINS replication occurs, remote control functions normally. This problem does not occur if the SMS site server and client computer reside on the same network segment.



CAUSE
When the remote agent is loaded on a TCP/IP client, the <43> extension of the client NetBIOS name is registered on the client. It is viewable by typing "nbtstat -n" (without quotation marks) at the command prompt on the client. This registration is picked up by the client's WINS server and is viewable in WINS Manager. On the appropriate interval, the <43> extension registration is replicated to any of the WINS replication partners.

If you attempt a remote control session prior to the WINS replication, the server running SMS Administrator cannot resolve the <43> extension of the client name.



WORKAROUND
To work around this problem, do one of the following:

 Configure the Site Server (or server running the SMS Tools) to use the same primary WINS server

-or- Keep the remote agent loaded on all computers all the time (once the extension is registered and replicated the first time, no delay occurs) Keep in mind that the extension can be removed from WINS by rebooting or unloading the remote agent.

-or- Use the LMHOSTS file on the server. For more information, please see the following article in the Microsoft Knowledge Base:

122057 How to Use Remote Control with TCP/IP

 Upgrade to Systems Management Server version 1.2, and set the default protocol to TCP/IP. For more information, please see the Systems Management Server 1.2 Administrator's Guide, Chapter 10, "Configuring Default Protocol Settings for Clients". Doing this allows remote sessions to use sockets, avoiding NetBIOS name resolution for the remote agent. This configuration is supported for Windows 95, Windows NT 3.51, Windows NT 4.0, and Windows for Workgroups (using MSTCPIP-32) client computers.
