DacCom.DLL Problem

[Tom Brady]

I am running WIN200 on this computer, and have no desire to change. I have a scheduled task which runs every morning, and have preciously had no problem withit. Suddenly, it doesn't run. I checked the Task Scheduler, and the message said it was turned off. I attempted to turn it on, but was not successful Ultimately Component Services told me that a file named "DacCom.DLL" was improperly installed, and had to be re-installed so that the Task Scheduler would run.

The file doen't exist on my computer, nor does it seem to exist on my WIN2000 installation disk..

I Googled the problem, and it seems to be fairly common. None of the solutions offered helped.

The program I want to run operates quite well when called up, but nothing will run from the Task Scheduler.

Anyone have any ideas how to restore "DacCom.dll"?

DacCom.dll, never heard of it, could be malware. Windows does have a DaCom.dll which is part of Digital Anvil Component Libraries software by Miscrosoft.

May want to try and reinstall it.

Right click on C:\winnt\inf\mstask.inf then slect install

Murf-
I did as you suggested. It got a little complicated, since the files the installation program was looking for were scattered all over; however, it seemed to end successfully with no error messages.

Unfortunately, it hasn't solved the problem. The Component Services still says that DacCom.exe hasn't installed properly, and must be re-installed.

It's a relatively minor annoyance, since I do have a work-around, but I hate to have a computer get the best of me. There's an answer there somewhere.

Did some research and it is a Windows file. Try re-registering it

START | WINKEY + R on keyboard

Type cmd

type

regsvr32 -u daccom.dll (hit <enter>)

Murf-
I tried re-registering the file with no luck. The failure message said that the module couldn't be found. I rewrote the command specifying where I knew the file to be (c:\winnt\system32) and got the same result.
I can't figure out what I'm doing wrong

May try replacing the file:

Download daccom.dll v1998.8.762.0

or maybe

HERE

Backup the existing one, then download and unzip into the

Winnt/System32 folder and say yes when asked to replace.

I did as you suggested, but it didn't help. Here is the sequence of events that transpire when I attempt to initialize "Component Services" (which controls the Task Manager, among other things)

I get 2 error messages. The first says "Unable to initialize application because (DacCom) is not installed properly. Please re-install this product.". The second error message is headed "Microsoft Management Console" and says " The selected snap-in did not initialize properly."

I've run SFC /scannow and re-booted, but that didn't help, either.

Ok then try the following;

Start | Run type cmd and enter

type in the following;

msdtc -uninstall

if it says OK then type

msdtc -install

This will uninstall and reinstall MSDTC service (Misrosoft Distributed Transaction Coordinator) Windows 2000 was originally intended for Server applications and does have many server applications in it.

Also for TAsk Scheduler to work it must be set to Log On as the Local System Account.

1. Right-click My Computer and from the drop down menu click Manage.
2. From the Services and Applications menu, click Services.
3. From the right scroll down menu, double-click Task Scheduler.
4. Click the Log On tab, select the Local System Account and Allow Service to Interact with Desktop options, and then click Apply.
5. Click the General tab, click Start.

Once again I have to report no luck. I ran the msdtc - uninstall, but didn't get an OK. I, neverthe less ran the msdtc - install, but nothing has changed.

So far as the Task Scheduler is concerned, the settings you recommend are in place, and have been since I first ran the program. The scheduler ran successfully for a long while, then suddenly stopped. Unfortunately, I didn't realize this for a couple of days, so I have no idea what I might have done to cause the change.

Interesting problem, haven't used W2K in years.

Try this:

1. Right-click My Computer and from the drop down menu click Manage.
2. From the Services and Applications menu, click Services.
3. From the right scroll down menu, double-click Task Scheduler.
4. Click the Log On tab, select the Local System Account and Allow Service to Interact with Desktop options, and then click Apply.
5. Click the General tab, click Start.

Sorry it's taken me this long to reply.
The steps you suggest, I've already taken. The settings were, and are, those you recommend. The message I get when I try to startthe Task Scheduler is "Could not start the Task Scheduler service on the local computer Error 1717:The interface is unknown."This is the same message I've goten before when I tried to start the Task Scheduler.

[Murf]

1. Click Start, click Run, type services.msc, and then click OK.
2. Right-click Event Log, and then click Properties.
3. In the Startup type box, click Automatic, click Apply, and then click OK.
4. Click Start, wait for the progress bar to complete, and then click OK.
5. Right-click Task Scheduler, and then click Properties.
6. In the Startup type box, verify that the startup type is set to Automatic.
7. Click Apply, and then click OK.
8. Click Start, wait for the progress bar to complete, and then click OK.
9. Exit the Services snap-in.

As Julius Caesar used to say: "Mirabile dictu!". It worked!

I did as you suggested, and it was not successful. I then removed another program from the Task Scheduler, which should have had no effect -- but---. I then re-booted, and the program I've been trying to run, now does so.

Thanks, Murf, for all the effort you've put into this

[Murf]

Thanks for letting us know. Computers are really strange and have a mind of their own. Don't understand how the fix worked as you said removed one other program and zazam it works.

Murf-
I have odten said : I wish I understood all I know about these things. Sometimes, pragmatism is the only answer. If it works, be satisfied
