Slow access in Outlook from VPN using an Exchange 2007 mailbox
Posted on 2008-10-24
VPN from office is fine, but Exchange 2007 is very slow when I use VPN from home. Exchange 2003 is ok.
newexc01pr is new Exchange 2007 server
ü Using cache mode
ü Defined newexc01pr and newexc01pr.na.tigplc.com in hosts file
ü RDP access to newexc01pr is fine
ü Pings are acceptable (Same as Exchange 2003 server)
v 10 minutes until login prompt comes up
v 15 minutes for folders to show up to date in cache mode. Cant access Outlook until completed. I was successfully able to send message after Outlook came back.
v 15 minutes to download Offline Address book.
v 15 minutes to access 2003 public folder from Exchange 2007.
Any ideas, what I can look at?
Could we have a DNS issue for newexc01pr?
Authentication seems to work, but extremely slow
Look into RPC service on DCs?
Should we look into difference for firewall rules for adcnaex01 and newexc01pr?
