causes 2wire wireless network card to work after installing then in my cases causes it to start thowing out SYNC_SENT's when trying to use IE or Firefox browsers. When this happens normal http traffic is halted. This is when using XP. May happen on other OS's. You can see this when you first connect up by going to a CMD (Dos box) and typing "netstat -p TCP 5"

I don't have wireless and it still showed up
its part of sbc\at&t installation to get dsl service to run. Keeping it from running under windows 98 can cause connection problems. some firewalls can promt you as to what to do when it is running. Suggestion: allow.
Component used in combination with wireless receivers like Speedtouch 120G. Not dangerous. Probably not necessary when you have enabled zero wireless configuration service in Windows
Installed Speedtouch ST120G wireless USB adapter. Everything fine. Afterwards installed Agnitum Security Suite Pro RC. And now I got an error from PRISMSVR at startup. But as stated by others everything seems to works fine.
belongs to Speedtouch 121G wireless USB monitor. Can be stopped from running without consequences for internetconnection.

On my Dell Latitude 800, on boot up, I get an application error from PRISMSVR.EXE and I close the application. I am using a 2wire link card which seems to work just fine.

Best practices for resolving prismsvr issues

A clean and tidy computer is the key requirement for avoiding problems with prismsvr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
