I am currently running MS Retail on 4 registers and 1 server. Awhile ago I started to receive an error message very spuratically with no consistency at all. It stopped for a long time and now it is back. The error message is: Write Error The System Does Not Recognize the Command. It will do this in the middle of a sale. It only happens on one of the 4 registers and never any of the others. Does anyone have a suggestion as to what this could be. Any help would be appreciated.
