DCOM Error

Hi,

We recently migrated our domain from NT4 to 2000.

One machine was a member server on the old domain and was migrated to the new domain and made a domain controller.  (not root DC)

On this machine I get the following error every hour or so in the system event log:

Source:DOM
EventID: 10004
Decription:  DCOM got error "Overlapped I/O operation is in progress" and was unable to logon [OLD_DOMAIN]\[ACCOUNT] in order to run the server {numbers}

I have checked all services and can not see anything that would use an account from the old domain.  

Can anyone shed any light on the issue??

Thanks for reading.

G

Overlapped I/O is a programming concept where an application or a device driver performs several input/output operations (like read/write files or communicating with a device) in the same time in order to increase its efficiency and use the system hardware properly. Instead of waiting for the hardware to respond to its request, the application may be able to perform other useful tasks that do not depend on the response of the I/O request. The I/O operation is performed in this case asynchronously. That is, you send a request and don't exactly wait for the answer at that moment - instead, when the answer comes, you get notified. This concept is paramount to a highly performant, scalable application (like Exchange for example).
Now, let's say your application sends a read file call to the hard drive device. If the request returns an error and that error message is ERROR_IO_PENDING than it means that the request is performed asynchronously and that the operation is not finished yet. This error message is the symbolic name for the error code 997.

For this type of error, Microsoft suggests that you contact the supplier of the running application. While not that useful, this suggestion indicates that in most cases, this is a bug in the application that generates it rather than a faulty configuration. Sometimes, workarounds are possible (see Q187770 for an example).

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

"was getting this: “DCOM got error "Overlapped I/O operation is in progress. " and was unable to logon <domain>\administrator in order to run the server: {ID}”. I had changed the administrator password. I had to run “dcomcnfg” and find the Dcom object that was referenced by the ID (just searched in the registry). Load up dcomcnfg then reset the administrator password."

The ID is the {numbers} at the end of your error message...

The guy searched the registry with the ID, and got the application...
