ok ive got the server restarted, no errors in event log. Then a few minutes later when I first try to go to the website, get 5 occurrences of these 2 errors in teh application log :
error ID : 2214
The HTTP Filter DLL C:\Program Files\Alwil Software\Avast4\AvIsaHlp.dll failed to load. The data is the error.
error ID : 2268
Could not load all ISAPI filters for site/service. Therefore startup aborted.
And at the same time in the system log, 5 of these, althought the process ID did vary :
error ID : 1039
A process serving application pool 'ExchangeApplicationPool' reported a failure. The process id was '6100'. The data field contains the error number.
After restartinh IIS, going to the web address triggers teh same 5 error's.
Any and all advice muchly appreciated. The only thing I've found so far is this :
