SQL version is 10.50.4279 for the publisher

The distributer is 10.50.4000.

The SQL Database that is replicated is running in SQL 2000 Compatibility Mode and was upgraded recently from SQL 2000(replication was rebuilt). I was able to script the task after rebuilding the replication but its suddenly stopped working in between the replication rebuild(last month) and now.

I'm not sure if theres anything else I can add.

I did use sp_removedbreplication to cleanup replication tables before the migration.
