SQL Server 2000 Cluster - Full Text Search Error

Hello All.

I have a Windows Server 2003 & SQL Server 2000 (SP4) EE cluster setup
using FTS on one table. It seems that when one node was failed over it
started throwing the following errors shortly after the crawl job
starts:

The crawl seed <MSSQL75://SQLServer/21ccaaa4> in project <SQLServer
SQL0000500006> cannot be accessed. Error: 8007007f - The specified
procedure could not be found.  .

Then a second later:

The crawl for project <SQLServer SQL0000500006> could not be started,
because no crawl seeds could be accessed. Fix the errors and try the
crawl again.

Then finally:

The end of crawl for project <SQLServer SQL0000500006> has been
detected. The Gatherer successfully processed 0 documents totaling 0K.
It failed to filter 1 documents. 0 URLs could not be reached or were
denied access.

Any ideas what is causing this?

*THANKS*
