Speed of Clients very slow

[rtshort]

I have never worked with Citrix before a few days ago. A friend of mine called me to redo his DSL connection at his server after an interuption in service, and he couldn't even get on the net.

He had 2 network cards in his computer. One he had going straight to the DSL Modem and the other to a wireless router. To connect to the Internet, he shared the other network cards connection. I think that we can all agree that this is a BIG nono.

I redid his connection just using one NIC and opened port 1494 in the DSL Modem so his client machines could connect. The connection works. I connect to it through MS RDC and it runs fine. He tells me that through Citrix, it a LOT slower than it used to be.

As I said, I've never used Citrix before so I'm not that familiar with it. I called myself going through all of the settings. I set it to 16 colors, and low on all of the rest. Am I missing a setting somewhere or is it just the fact that it is running though the DSL Modem now?

Thanks.

I'm not following the last line.

"Am I missing a setting somewhere or is it just the fact that it is running though the DSL Modem now?"

What kind of Internet connection did they have before? What is the measured latency of the connection? What is the upstream bandwidth of this DSL Connection? Are the connections slow on the private network, or only over the Internet?

Hi Patrick,

Thanks for the response.

I was wondering if I may have missed something in the settings of Citrix that may have made the connection slower than normal.

The Internet connection should be the same speed. They just had a lapse in service because the ISP (BellSouth) claimed that they were running a virus on the server that tried to steal passwords or something. BellSouth turned off thier Internet connection for a few days and then turned it back on.

After I used MS RDC to get into it, I found that the "server" had a process that was taking up 99% of the CPU. It was "spoolsv.exe".

After doing a search on Google, I found that this may be a virus or malware. I think that is the case. The server was just overloaded and couldn't handle all of the request.

I'll update this query when I find out the "truth"..

Thanks for your response.

That is the Printer Spooler Service, which may act like a virus sometimes when it gets possessed, but it is part of Windows responsible for processing print jobs (NOT A VIRUS). This can be resolved by stopping the printer spooler service, deleting files from C:\WINDOWS\system32\spool\PRINTERS\, then restarting the service.

This often happens when using non-Microsoft Printer Drivers, i.e. ones downloaded from the printer manufacturer.
