c:\powerchurch\pcplus9\pcplus9.exe is not a Visua FoxPro.exe

Post by **Tracy** » Tue Nov 30, 2004 4:02 pm

I want to be sure this is clear for our research.

Installed 9 onto server. It works.
NetSetup9 on workstation, open PC+. It works.
On workstation still, close PC+, open PC+. It fails.
Goto server, open PC+. It fails.
Shutdown and restart server.
On server, open PC+.

Does it still fail on the server at this time?

Have you tried installing PC+ on a stand-alone computer?

See if that works. If not...its possible that your install media is bad/corrupt. You might ask for a replacement, if you haven't already.

Are there other application programs on the server that work on the clients?

If I remember correctly, XP home does not have a lot of the network connectivity/security that Pro does. I'm running XP Pro SP2 on 10 CPUs with my server running FreeBSD.

Do you have a client CPU running XP Pro? You might try connecting it to the network/server and see if it works.

>>Yes it still fails at reboot.

>>Have you tried installing PC+ on a stand-alone computer? Yes I have. >>It run successfully.

>>I have ask for replacement. Install it on a diffrent server on Windows XP. Run the workstation and got the same results. The only thing that is static through the test was the Wireless Router.

Although my XP client are Home edition. I also have windows 2000 server/Pro and continue to get the same results.

I notice that the bytes size of the pcplus9.exe changes after the client tries to access this very file.

>>Before 12,278 11-17-2004
>>After 12,452 11-17-2004

It appears the exe. by the client is getting corrupted.

One of two things might cause this.
Compressed folder where the EXE is being installed, and faulty memory is causing a change.
More likely; There is a virus attaching itself to the EXE.

I doubt the first option is valid. (Although I don't understand the compress folder)If I had faulty memory this would only occurr on the server that has the bad memory or cash. I have been able to recreate this problem on diffrent servers and OS. But the second option could be valid. We will purchase NIV and see if there is a Virus. Thanks for your help.

There are a few online scanners to test the theroy before you rush to make a purchase.

Just a heads up. Installing an anti-virus software onto a system where the User logged in has administrative rights to the workstation but not the server it logged into causes other problems. Be sure to install software that works as a service like the anti-virus software as the administrator of the local workstation AND either, not logged into a server, or administratvie rights to the server. It will reduce headaches later on.

RE: Online Virus scan

Here are a couple of links to try.

Trend Micro:
http://housecall.trendmicro.com/houseca ... t_corp.asp

Panda Antivirus:

NB: These sites are not associated with PowerChurch in any way, however, we do use Panda Antivirus on our internal network, and it works really well.

We have found over 60 files that have been infected on every machine on our intranet. We think the virus is the reason for my errors. Hopefully you all will keep this in the logbooks so no one else will have to go through the horror that I have. Thanks a lot.

Sad to say, this points out the necessity of a good antivirus program on all machines on a network. Firewalls do not do it alone !!

Altogether too true. Especially with the way many client side anti-virus programs work, this can be a full-time job depending on how many computers you have on the network.

I'm working on an automated script that will keep all of our 10+ computers updated without operator/user intervention.

I'm not there, yet.

I've got Panda Antivirus on our proxy server, and it does a great job. We also have either Norton AV or F-Prot on each of our individual machines as a backup. Panda catches just about everything, but occasionally a brand new virus will slip through before the proxy server gets updated, and the local machines catch them. That's very rare though.

You may want to look at some of the Symantec offerings that provide complete control over all the machines from a central server.

No matter what virus protection you use. Try to be sure it can be set to not check DBF, CDX, and FPT files to help avoid data corruption and random errors. On slower systems (heavy load times of network, defragmented hard drive, processes currently running on the system, etc.. are all factors that effect system speed and performance) the a/v might not let the file(s) go fast enough for the program, which can throw and error, possibly causing corruption.
