Users encountering delays, sometimes disconnects while using MSN Messenger 8.1 on terminal server 2003, average user has over 100 people on his/her contact list, some users have over 200 in their contact list, one person has close to 500 in their contact list.
While they are communicating with their customers they frequently have these intermittent delays and sometimes disconnects where the users have to relogin.
2003 active directory environment, terminal server 2003, office 2003, trendmicro officescan server 7.3, 2 dualcore amd processors, 8gb ram, hardware raid-10, gigabit network for all servers, 100mbit for all endusers, endusers are connecting through Remote Desktop Client or through 2X thinclients. Right now this terminal server only has 5 users on it.
my documents folders are redirected to iSCSI storage using openfiler.
pfsense firewall, xeon 2ghz, 1gb ram, dual wan connections, T1 1.5/1.5, DSL 8/1, using policy routing, users on terminal server are utilizing dsl connectivity for surfing the net and MSN, network utilization is below 30%, cpu utilization is below 15%
I have no idea what is going on, I am trying to tell them it could be due to their large number of contact list or could be the msn server their account is housed in.
I have searched the web for a long time now and at this point I am looking for help from the technical community.
