Automatic updates crash

This morning wuauclt.exe was crashing many times until I stopped the
service.

The event viewer gives me this information:
Application Failure wuauclt.exe 5.8.0.2469 in wuaueng.dll 5.8.0.2469 offset
000d4fff

Naturally, when I wanted to run MSBA 2.0.5029.2 it wasn't able to and
returned
{4884D6F5-A472-439A-87C6-5F266ED16321} 2005-07-13 08:42:03+0200 1 148 101

Synchronization Error: Agent failed detecting with reason: 0x80248011

Here is a sample of the error recorded in windowsupdate.log:
