Outlook Anywhere error trying to enable

[ndnalibi]

Hello,

I am running windows server 2003 x64 with Exchange 2007 SP1.

When I try to enable Outlook anywhere I get the following error:

Enable-OutlookAnywhere : The Active Directory object for virtual directory 'IIS
://mail.XXX.com/W3SVC/1/ROOT/Rpc' on 'MAIL' could not be c
reated. This might be because the object already exists in Active Directory. Remove the object from Active Directory, then re-create it.

I have rpc over http installed (and removed and re-installed it also). I tried to delete the rpc directory in IIS management.

I receive the same error through shell or console, but can not find any relevant information online that discusses this specific issue.

Any help or direction would be appreciated.

Thanks,

Bill
