I did a bit more research and I found this in the MSDN Library

The error detail for -2147200993 is:

SPERR_RULE_NOT_DYNAMIC : An attempt was made to modify a non-dynamic rule.

Hex number...

This is the original message from the Merge agent error window.

LAST COMMAND IS:

{call sp_MSdummyupdate (?,?,?,?,0)}

ERROR MESSAGE IS:

The process could not deliver dummy update at the 'Publisher'.
