I have a 2003 x86 server, all patched up, recently had a bespoke software package updated, since then all the clients reporting long lags when accessing the server data (bespoke clients installed locally), now the software company is blaming the server for speed, but I can copy a 1GB file over the LAN to server in around 15 seconds on Gigabit, so it doesn't seem like there LAN is slowing the software down.
Looking at the server, there are no major errors, and all other software such as Outlook to Exchange works fine, but the manufacture still insist that the server and the network is at fault, what software can I run to generate tests to show the server and the network is working fine ?
Prior to the update, their software on the server with their clients software locally all worked ok, but it is difficult to try to convince them their software may be to blame for this, and the speed issue came after the update because the next day everyone noticed this massive lag.
Thanks for any help on this.
Server is on Q6600/4GB/RAID10 on 4HDD
