Re: Slow server response. Is it my box or is it the network.

Hey guys need some help....

People are reporting slow outlook response. I am getting ready to run the Exchange Best Practices Analyzer to see if anything may be misconfigured. But my network guy says that the network is reporting an excessive amount of TxPause packets from our mail server and explaining our server can't handle the amount of requests coming in so its sending out requests to slow down the requests. Here is the data he gave me:

Port Send FlowControl Receive FlowControl RxPause TxPause Unsupported
----- -------- -------- --------- --------- ---------- ---------- -----------
4/17 on on desired on 0 97920 0

could that be an accurate assumption? Looking off hand, it doesn't appear that the machine itself is sluggish. Its a 4 proc 3.4GHz box with 3.5gb ram, with about 700 users. The cpu is around 10% PF is 1.3g, and its using about 2gb ram.

Any insight would be helpful as I am not so much a network administrator.

Thanks!

That looks like a cisco switch you got there, I would advise your network guy to do a show interface on the port the mail server is connected to, it would be helpful to see if any packets are being dropped, CRC errors, etc.. Also do you have just a single network card in the server or are you ether channeling them? I would also like to know if the the switch port the mail server is connected to is hard coded for speed and duplex, one major problem could be if the switch is programmed for 100 full duplex and the server is set to auto-negotiate.

Also you do not mention the version of exchange, any additional software running on exchange, etc...
