Outlook 2003 Client to Exchange through Pix 7.1

v-naughton — Fri, 21 Feb 2020 08:46:43 GMT

Hi,

We have an Outlook 2003 clients that connect to an exchange server through the PIX but are experiencing 40 to 50 sec delay in being prompted for authentication. Firewall rules allow the client out for any connection to exchange. Clients function fine outside the firewall.

Any ideas what the problem could be.

Thanks,

Vincent

hi vincent,

check the PIX`s CPU utilization. How are the other applicationg doing through PIX?

have you reduced the nat table idle-timeout, if so then increase it to atleast half an hour. also update me about the PIX model.

Thanks Aashish,

Will check those. The Model is a PIX515E. It is set up in failover (using the failover cable rather than LAN failover....waiting to get new nics in the PIX's).....it is running version 7.1......

Thanks

Vincent

why don't you just set up OWA and have them use webmail. All you have to open is port 80 and or port 443. It is a lot easier to deal with rather than using outlook.
