Here's the setup:
Code:
Phone Line --> SERVER_PC --> HUB --> PC1 (Direct)
\--> PC2
\--> PC3
Okay, now the problem. The store uses inventory software (DOS-based application) that is installed on the server, along with QuickBooks. If either program is run on the server, it launches with no problem and pretty quick. However, if any of the 3 other PC's run the program (they use the .exe located on the server to run it locally) it takes forever to populate the inventory or load the QuickBooks database. The strange thing is, one of the PC's seems to almost always be -much- faster than the other 2, but still not at fast as the server.
This issues also just started poping up last week, it hasn't always been like this. It is very frustrating to check inventory when a customer is there waiting.
Things I have tried:
-Disabling anti-virus software
-Trying a new PC inplace of the ones going slow
-Running a new network cable directly from the hub to one of the slow PCs
-Reboot the hub
Can a failing hub function, but function slowly?
If I have a crossover cable, how do I easily set up a connection from the server to one of the PCs to test that quickly to eliminate the hub as a possibility?
Any other ideas? Im not sure why this issue would pop up out of nowhere and since the whole PC was replaced it is definately in the networking or the server itself I would think.
