Connection issue

Hi,

I'm hoping someone has seen this issue in the past and can help me out.  I have SRM 5.5 set up between two sites.  On the protected site when I make the connection to the Recovery site I have to put in the hostname\administrator and then the password to connect, administrator by itself with the password does not work.  Going the other way (recovery to protected) when I connect I only need to put in administrator and then the password. 

Thanks,

Thom
