I get the afore-mentioned error on some of my Merge Agents but data is still being replicated to the main server. I don't understand how this could happen. When I select Error Details it shows that data is uploaded but errors out after the upload stage. On agents that don't error out it shows messages of uploading data and also "Merged Data". I am running SQL 2000 sp3a on a windows 2000 server box. If anyone has an idea or perhaps a place where I could look to find some info that would be great.
