TASKLIST ERROR: Class not registered.??

[contrex]

That first section looks like the command prompt 'C:>' starting line, and he's just copied and pasted what ghostdog has suggested instead of CDing to the directory and inserting the command after the '>'.

Yes that's what I thought.

If he is doing something similar to run TASKLIST, maybe that's why he gets "class not registered"?

[gumbaz]

OK Sorry bout that.. i CD to the directory now.. and now its working giving the correct checksum of  70363a3228df8fc8cff4e78f36b31c45 tasklist.exe

but tasklist is still not working though...

[contrex]

The Code Wizard speaks... This your task young Gumbaz... (in other words I give up). Something is damaged, that's for sure! Sure sounds like your registry.

Does it work from the command.exe prompt rather than the cmd.exe one? (type COMMAND at the prompt to start it and EXIT to quit)

I see you posted this as "Deviouz" on the Techspot forums, and got pointed towards a page about regsvr...

[ghostdog74]

last thing you can try...the dlls that tasklist loads up is as follows...(on my machine)

Code: [Select]

ntdll.dll, kernel32.dll, msvcrt.dll,ADVAPI32.dll, RPCRT4.dll, USER32.dll,GDI32.dll, MPR.dll, ole32.dll, OLEAUT32.dll,Secur32.dll, WS2_32.dll, WS2HELP.dll,framedyn.dll, NETAPI32.dll, DBGHELP.dll,
VERSION.dll, ShimEng.dll, AcGenral.DLL,WINMM.dll, MSACM32.dll, SHELL32.dll,
SHLWAPI.dll, USERENV.dll, UxTheme.dll,comctl32.dll, comctl32.dll, xpsp2res.dll,
CLBCATQ.DLL, COMRes.dll, wbemprox.dll,wbemcomn.dll, Winsta.dll, wbemsvc.dll,
fastprox.dll, MSVCP60.dll, NTDSAPI.dll,DNSAPI.dll, WLDAP32.dll....
you can try to load each on of them...using regsvr32 <dll>....just $0.02

[gumbaz]

its not working from the command.exe prompt either..

@ghostdog74
so i just do this for each .dll then in the CMD..??

Code: [Select]

c:\>regsvr32 ntdll.dll
c:\>regsvr32 kernel32.dll
ect...

I think you are right ghostdog74, it seems that such an error is caused by a system file (DLL) that the program needs either not existing on a system, or being an older version than required. Since tasklist (obviously) works on a new XP install, maybe an important system dll has been overwritten by a previous version. I thought Windows file protection was meant to prevent that? of course its warnings can be ignored by reckless users...

Or another possibility...!!! --- guess what --- just doing a bit of Google searching --- tasklist and dll being the pair of words I used...

This fits very well indeed with my unease at a genuine tasklist executable surely not needing any registration at all...

tasklist.dll

Tasklist.dll is TROJ_ADLOAD.IE.

(2)

http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=TROJ_ADLOAD.IE&VSect=T

File type: PE

Memory resident:  Yes

Size of malware: 88,576 Bytes (.EXE file); 66,048 Bytes (.DLL file)

Initial samples received on: Aug 3, 2006

Payload 1: Downloads files

This Trojan arrives on a system as a file dropped by other malware, or downloaded by an unsuspecting user when visiting malicious Web sites.

Upon execution, it drops a file named TASKLIST.DLL, which is also detected by Trend Micro as TROJ_ADLOAD.IE, in the Windows system folder.

To ensure its automatic execution at every system startup, it registers itself as a service by creating the following registry keys and entries:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\AutoUpdate
DisplayName = "AutoUpdate"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\AutoUpdate\Parameters
ServiceDll = "%System%\tasklist.dll"

(Note: %System% is the Windows system folder, which is usually C:\Windows\System on Windows 98 and ME, C:\WINNT\System32 on Windows NT and 2000, or C:\Windows\System32 on Windows XP and Server 2003.)

Could this be a promising line of enquiry?

Gumbaz, did tasklist work once upon a time, or have you just started trying to use it?

ominous silence...

ominous silence...

i think OP should be trying out  your latest post, ...lol...give him some time..maybe he will post back. I hope he is using his AV now.

I wrote this last Friday, 4 whole days ago...

I wonder if a virus did it?

The OP wrote this...

I use ZA ISS like a paranoid crack head

What, he fires it up and then goes outside with a knife and holds up old ladies for their purses so he can do it some more? 

Crack heads are not generally noted for their prudence, patience, ability to listen to advice or follow simple instructions, etc... 

Try typing "Zone Alarm crap" into Google... or "Steve Gibson" and an uncomplimentary epithet

SUP Yallz..
thanx 4's yurz helpz so far.. but it don't seem like im having any luck getting it to work..
i don't relay remember using tasklist on this PC before.. i just found out about it a few months ago..tried to use it and got that error so i just forgot about it and went on my marry way..just used it on another pc or in a VM..

i did regsvr32 on all those dll's and still no luck.. still get that *censored* error..!!

i aint gots no viruses  that you think i might have contrex.. ZA ISS uses kaspersky AV database so im sure if i did have something it would have been picked up already.. i scan my system every other day or so..
being a paranoid crack head just means im overly cautious & protective about my pc and security settings.. don't get all analytical on me in stuff..

anyway i guess im just SOL on this one guys.. i really dont know what the problem is with it.. becuz it works just fine on all my other PC's which i used the same XP DVD to install the OS with..

so i guess my only other option would be to just get a new HDD and start all over again huh....

[contrex]

Why a new HDD? What about a repair install followed by SP2?

[gumbaz]

how i do the repair install just for a lil ol tasklist app..??

[contrex]

You don't know what else is wrong. Your registry could be crap. Tasklist could be the tip of the iceberg. How do you even know your AV stuff is working like it says it is? You could have a squillion viruses you know nothing about. Face it, bro, your system is broken.

[gumbaz]

SO WHAT I DO THEN MAIN...

It's all on this site in the help, you only have to look.
