Cannot offer remote assistance to Vista

[Urvin]

Hi ,

I am in a windows 2003 Domain and have the following problem when using

remote assistance:

I can offer remote assistance to all Xp workstations but not to any Windows

Vista workstation. When I offer remote assistance to a windows Vista machine

I receive an error stating that " your offer to help could not be sent".

Furthermore the following event is registered in the novice machine:

Hello,

The RA should be disable by default, u can enable by group policy.

The default properties of the RA exception.

1. Msra.exe application exception

2. RAServer.exe(the RA COM server) application exception.

3. DCOM Port 135

4. uPnp enable for communications with uPnP NATs
