Problem with Locked Files

By efmooney ·
I am having an issue with locked files on a Windows 2003 Server. Consistently files become locked as open even though they are not. I know how to kill the locked files on the server, but this is happening way too much for that to be a feasible resolution. I believe what is happening is that during the creation of a file, something interrupts the network connection, the user gets an error message, and is kicked out of the file. Now the server thinks the user is still in the file, so the user cannot access it. I am really not sure how to proceed. I figured that there may be issues with the network (esp since some of worktations are wireless), but this is happening from multiple workstations. I was thinking it could be the switch, but do not have an easy way to test this.

So, just looking for maybe a little advice on a direction to go forwared with. Any help is tremendously appreciated.

here are a few idea's that may help you.

Break the network down into wired and wireless, is it just the wireless PC's that are locking the files?

If it is the wireless PC's make sure that they aren't too far away from the access point and that the access point isn't getting too much interference (channel 11 is used by microwave ovens, you got a microwave oven near by?) or been obstructed/reflected off walls or other objects.

Also most wireless access points have a setting where you can enhance the signal strength, if your access point does have this option then try that.

Setup a ping to run on one of the effected PC's (open the command console and type ping <server IP address> -t > ping.txt.

Let it run for a while (even up to 15 minutes), stop the ping (ctrl + C), open the text file and look at the response rate.

If you are getting major timeouts then it's a good chance that is your issue.

If it's the wired network also and always the same PC's doing this then take a look at their network card and see what speed they are working at and also how many error are occurring on the card.

Do you have any redundant switches? make sure spanning tree is enabled, if the switches are managed then you should be able to look at how many collisions/errors are occurring on the ports.

What is the cabling in the office, and in switch room like? Maybe try some new cables and see if that makes any difference.
