Hi ,

Even We are facing similar problem. we have migrated our windows server 2003 enter to WK3 ent
due to some Hardware issue. MX its located in different location (US),
we have established VPN tunnel between my office to US office through Netscreen firewall.

Outside users accessing mails outlook 2003 through RPC/HTTP. Before migration everything was working fine.

After Migration internal users are able to connect outlook very fast. but whenever we try to connect outlook
from outside the office network , it takes long time to connect to the server, but OWA its working fine.

I have checked all RPC settings, Netscreen firewall settings and compared old server and new server configuartion everything is similar

Anyone can help me?. is it could be the problem with MTU size or anything else?

I added the parent company DNS server to our DHCP and WINS and now Outlook connects.

Do you receive an error? Depending on how your accounts are configured in the parent company, you may need to supply different credentials to access your mailboxes.

You can try logging on to OWA (http://excahnge_server_name/exchange) to confirm that your credentials work.

Instead of connecting through a firewall, the parent company might consider using RPC/HTTP(S) with Outlook 2003 in cached mode which allows you to connect to Exchange Server 2003 securely over the Internet.
