I have 3 Servers with SiteServer 3.0 Service Pack 4 installed as:

1. C: & Data E:
2. C:
3. C: & Data D:

Server 2 is where the catalog builds occur. Server 1 is where the catalog 
is propagated to. I have the default website pointing to server 1 for 
search results.

Server 1 is being replaced by server 3. Therefore I propagated the search 
catalog to 3 yet I get the following result.
"Invalid column name found in the Columns Property"

As per MS KB Article ID: Q197519 I am recommended to edit the registry. 
The Registry exactly matches the directory structure.

1. E:\Microsoft Site Server\Data\Search\Config\DEFINECOLUMNS.TXT
2. C:\Microsoft Site Server\Data\Search\Config\DEFINECOLUMNS.TXT
3. D:\Microsoft Site Server\Data\Search\Config\DEFINECOLUMNS.TXT
 
I am unsure what the next step should be. Could someone please assist?
