IIS IP and domain name restrictions - automated access denial

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. 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"

Re: IIS IP and domain name restrictions - automated access denial

Do you have the MOM 2005 IIS Management Pack installed? 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.

Cheers

Re: IIS IP and domain name restrictions - automated access denial

Note that the current version of the MOM 2005 MP does not have this feature
anymore. You may wish to consider upgrading.
