Dissolve in ArcMap gives ERROR 999999

Question

The Dissolve tool is not working for me when I use ArcGIS Desktop 10 to dissolve a shapefile.

It says:

ERROR 999999: Error executing function.

It works perfectly when I use version 9.3.

Any help?

I have found that not all tools work when your geoprocessing environment is set to run in the background. I believe that Dissolve may be one of these. Change you GP environment to Disable Background Processing and then give it a try.

I have not tested this but may be worth a try

Try this: Run Repair Geometry 1st and then run Dissolve.

The 99999 error can be caused by any number of reasons; system resource availability or dataset issues are a couple possibilities. While disabling background processing may seem to have solved the immediate problem it actually is only a workaround to another problem. All tools (aside from the 5 or 6 which absolutely cannot run in the background) do function through background processing - there however might be one off cases or bugs for a particular situation which causes tools not to run. In general, the dissolve tool functions fine through background processing.

I have found that I need to go into the environments and specify that the processing extent is the extent of the shape file in question. For some reason the default extent is off.
