I have a Dell 2.0Ghz running on XP.
After I read the posted here,I tried TASKLIST /SVC on CMD window; but I've got only an error message saying:

'tasklist' is not recognized as an internal or external command, operable program or batch file.

Why is TASKLIST /SVC not working on my XP?
I'll appreciate your help.

Tasklist is only in XP Pro, I'm guessing you have XP Home edition. You can copy it over from an XP Pro system, if you have access to one. You might also be able to find a copy on-line if you search.

Thank you, Leo. Yes, mine is XP Home.
While searching for TASKLIST.EXE, I found great free tools from the following site:

http://www.sysinternals.com/ntw2k/utilities.shtml

Free tools of this sites such as Process Explorer, TCPView, FileMon, RegMon seem very good.
Would you check them out and give me opinion?
I'll appreciate again.

I *highly* recommend sysinternals. In fact, you'll find them mentioned in several of my articles, and on my recommendations page. The tools you list are part of my "take everywhere with me" arsenal :-).

my sygate peronal pro firewall tipes that it is a critical problem and blocks incomming messages to svchost.exe. firewall desdcribes it in that way: 03/26/2004 20:56:08 Intrusion Detection System Critical Incoming TCP 192.168.11.52 192.168.11.191 svchost.exe 4 03/26/2004 20:56:08 03/26/2004 20:56:08
is it wrong if firewall blocks these connectings?

No, it looks like the firewall is doing its job. Further, based on the IP addresses, it looks like one of the other computers on your network may be infected with a virus.

THANKS IN ADVANCE.

No way to know, since you didn't say where you found it. There are such tools ... I would start at Symantec's anti-virus site and download one from there. http://ask-leo.com/d-symantecavc

Best of luck,

I'm having problems with IEXPLORE.EXE and EXPLORER.EXE...
I think both are corrupted, because when i'm opening certain folders with images or photos or even larger number of files it goes like this:
- "EXPLORER.EXE (or sometimes IEXPLORE.EXE) generated errors and will going to close"

how can i solve this problem?
I think just reinstalling Windows is not enough, so i appreciated if you could give me an answer.

Big Thankx
