I am trying to resolve a problem on my client's network: 4 Windows XP Pro systems, 1 working as a server only; 8-port Netgear Gigabit switch connetcing all together and to the internet through a Sonicwall then DSL using Cisco 685 (?) DSL Modem. New cables, new switch, new SonicWall, new computers as of about 3 months ago. Cables run on the wall not in the wall, up through dropped ceiling with flourescent lighting. Problem: PeachTree consistently has delays when entering data on two of the three systems (databases are shared on the "server"). The other workstation shows no delays in PeachTree. No ther apps show any performance issues as far as we have been able to determine. Workstation where PT works well happens to be the closest one to the switch / firewall / DSL, but the 'server' is in another room next to one of the other workstations. I thought it might be interference on the cable from the lights' ballasts but it would have to mean that two of the cables were similalry misplaced - possible but unlikley. We purposely ran the cables around and not over the lights. Next I plan to exchange a 'working' desktop with a 'delays' desktop to see if the problem follows the location or the cmoputer, but I am hoping someone has another idea??
