In addition to all the great questions and suggestions so far I would ask, if only one person is trying to do something does it work ok or is it ALWAYS slow no matter what?
If it gets slower and slower with more people you could be dealing with a variety of network issues with a start being the firewall getting overwhelmed. As Al pointed out, a network trace would probably be handy to get. Do it from the client side, see what packets are getting responses and what the timing of the responses are. The outlook/exchange is a pretty complicated dance so there are many different places issues could be cropping up. I also agree with Robbie's suggestion of dropping the firewall for the purpose of the testing. If they are being assinine about it you can say... Well thanks, the performance from our side is great, if you guys would like to work out your performance issues, you know what needs to be done. joe ------------- http://www.joeware.net (download joeware) http://www.cafeshops.com/joewarenet (wear joeware) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Salandra, Justin A.

If it is a very old firewall then chances are that it may be causing issues.... Will they drop it for a testing period to see if it makes a difference? If it is for their benefit, i.e. their clients then they may? At least that way you could say it's their firewall and they need to update it to gain performance? -----Original Message----- From: Salandra, Justin A.

[mailto:[EMAIL PROTECTED] Sent: 23 March 2004 14:58 To: ActiveDir (E-mail) Subject: [ActiveDir] Exchange 2003 and Firewalls I have a facilities that insists on having a very old 3Com Firewall between our organizations. On his side of the firewall is has 400 + outlook clients, on my side I have the Exchange 2003 server and the Global Catalog Servers. Clients are taking an extremely long time to connect to mail and access resources. None of my other 9 facilities have this problems and the only thing different is that none of the others have a firewall between our two organizations. What ports do they have to open to allow proper communications between their clients and my servers? Justin A.
