I have a Windows Network with Windows clients (42 XP Pro SP2 and 8 W2k Pro SP4+). All the workstations are 500 MHz or better, 256MB RAM or better, and run McAfee VirusScan 7.1, all have 100mb NIC some embedded, some 3C905's. Our primary server (W2k) was a Proliant 800, dual 550MHz PIII's, 1 GB RAM, 52GB raid array using a SL-2 controller. We recently setup a new server (W2k3) on a Proliant M110 - 2GHz cpu, 1GB RAM, and a 104GB raid array on SA531 controller. Only major difference is NIC on old server is Intel Server 100 and new system uses the embedded Broadcom 10/100/1000 NIC. Network is all Cat6 in a new building, we have been here 6 months.
Two weeks ago I started moving files off the old server to shares on the new server. Used multiple test accounts and multiple machines to test connectivity. No problems.
Now I have moved the financial department, Friday, and discover that 'Excel' opens slowly, hangs for up to two minutes at random times during the day. Affects all users and all of the various workstations. When it is good the new server is faster than the old, BUT when it is bad they are pulling my hair out. (Not that I have that much to spare). I use DNS not WINS, ComputerBrowser is disabledon all machines, I have the same 'Hosts' and 'LMhosts' files on all workstations. I have run DCDIAG, and every other tool I could think of. Tried with the firewalls disabled - no change. re-enabled. Any suggestions will be greatly appreciated. Thanks.
