IIS IP and domain name restrictions - automated access denialHello
I've had some issues with IP addresses appearing to be automatically added to IP address restrictions (at the 'web sites' level) and being denied access on an exchange front end server. This is affecting OWA users as it prevents access to their email. Does anyone have any suggestions as to what could be causing this? Thanks Chris I think I've found the problem -why didn't I think of this being the cause???
;-) "IIS 5.0 or IIS 6.0-based Web servers that have Microsoft Operations Manager (MOM) 2005 and the IIS Management Pack installed may randomly add IP address and domain name restrictions to all Web sites on the local computer" http://www.kbalertz.com/kb_912156.aspx Show quoteHide quote "ChrisH" wrote: > Hello > > I've had some issues with IP addresses appearing to be automatically added > to IP address restrictions (at the 'web sites' level) and being denied access > on an exchange front end server.

There is a feature
in the original MP (not the current version) that can automatically add IP addresses to the denied access list if there are too many 401s received from particular remote IP addresses.
