I installed a new 2003 server inplace of my old 2000 server. I have a basic msaccess database app that all the stations on our net share the database file stored on the server. Opening the file from the stations (all xp pro, DNS configured to the server) used to take only 5 seconds on the 2000 server. Now on the 2003 server it may take 30 to 45 seconds to open the file and data input crawls. I setup a old computer I had, a win98 station 500Mhz 8.4 gig drive 64mb ram, shared a directory put the database on it and accessed the file from there on my xp stations and the file flies. The server is a p4 3.0 1gb ram 3-32gig scsi drives on and adaptec raid-5 controler. The server Screams if working on it. I have tried different net cards. No help. This has to be some type of secuity issue for 2003 or comm setting for tcpip but I have done 30 2000 servers with active directory and I have setup DNS the same way. Any help anyone. I have talked to 3 other system admins with the exact same issue and they are all waiting on me to figure out the fix. Professional Computer Systems

Did you check your server's NIC settings for speed/duplex? If not, go have a look and ensure it's set the same as the workstations. You didn't mention your network speed but I'm guessing it's 100 MBps so ensure your NIC is set to 100/full duplex and see if that doesn't improve things.

How is your DNS setup??? Improper DNS settings can generate this kind of network delay.

Maybe this will help =========================================== New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003 http://support.microsoft.com/kb/328890

I'm having the exact same problem, only my problem is involving Smart Shop (an old and dead accouting software) and the Interbase server that came with it. On a P.O.S. Win2k server login times are under 2 seconds, on the new shiny Win2k3 server login times are roughly 28 seconds... I'll have to look into the TCP ACK thing and I'll let you know how it goes. I was putting off sniffing the network traffic but after reading this I'm going to do more tinkering.

I am having basically the same problem with on a 2003 server. The 2003 server had a access database it was being shared. The response time from the database became very slow especially they download 16,000 records to it. I mean painfully slow. We also suffered drive disconnets damaging the data on ocassion. I look for the registry entry above but it does not exist on this server. Not sure how to proceed.
