Hi, we have a problem with our exchange server.
Local logons through the LAN seem to go by reasonably fast. Using a
native Outlook 98 client accesseing our Exchange Server with MAPI/MSRPC.
We are a TCP/IP only shop, no NetBIOS/NetBeui.
The problem lies with our remote offices, when logging on, there are
some extreme delays. We've done some packet capturing and found the
0-10 sec authentication traffic
10-30 sec nothing!
30-40 sec synchronization traffic
The Exchange server is way under utilized (Compaq dual PIII), the
users' mail stores are small, regualar Internet traffic between the sites
is extremely fast (low latency, high throughput). The clients are all the
latest Outlook 98, using Exchange MAPI to connect to the Exchange server.
We've disabled the NT Authentication on the logon prompt (brought logon
times to withing 40-60 seconds). But there's still a large delay. The PDC
and BDC are at our location, and the exchange logon uses a this domain.
Has anyone else experienced this before? Can anyone help?
