Problem: Some customers, after upgrading to LDMS 9.0 and trying to remote control machines, are getting error: Unable to send a request to remote computer.
Cause: The root cause of this particular issue was the Microsoft.VC90.CRT.Manifest file and the msvcr90.dll library in the ServerManager folder. The new version 9 RCViewer uses a newer version of the Visual C++ libraries. The problem machines all had .NET 2.0 SP1 installed.
Resolution: Updating the machines to .NET Framework 3.0 SP2 has resolved some issues.
