Hi there,I'm trying to manage folder permissions using the PFDAVAdmin tool but when I enter one of my exchange servers (it's a cluster) and then one of my domain controllers, logon credentials are domain admin, I cannot view either the Public Folders or Mailboxes, I get a 503 Server Unavailable and when trying to access the mailboxes I get "object reference not set to an instance of an object".does anyone know what these mean? I've tried both servers in the clsuter, and both give the same result.

What account are you using to run the tool?http://sdrtech.blogspot.com MCSE: MCITP - Exchange Admin: MCTS - SQL 2005

Hello,Are you giving node name while connecting in PFDavAdmin? Try giving virtual server name.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Hi,I'm using the domain admin account.Amit,thanks that's got me a step further however I can't expand the mailboxes now I get the following:could not expand http://servername.localdomain/exadmin/remotedomain/usernameOur remote office's domain had Exchange setup first, then we set it up in this office and have the services linked to serve the same external domain but internally their seperate domains and it always seem to think the remote domain is the primary, any ideas on this?EDIT:i've tried opening the mailbox directly using the full correct path, and I get "Name cannot begin with the 0 character"

Ah, i've cracked it now, after googling the last error I posted, i read about installing .NET Framework 1.1 on my workstation, and now I can connect!
