Any help appreciated,

I am running SBS 2003, I have loaded all critical updates
over a period of time without problem, now however, the
web browser appears to have stopped responding when in
windows update mode. It will list the updates available
but completely fails to respond when the Install updates
button is activated. Additionally I have noticed that the
browser hangs when used to view reports in the Management
Console, such as the backup reports or help files.The
browser version is 6.0.3790.0 I am now unable to update
the server with any critical updates.
Thanks to anyone in advance
Mike
