Running MOSS 2007 SP2:
When I click Shared Services Administration: TEST SSP > Search Administration > Scopes > View Scopes I get an error message in the area that the list of search scopes would normally be located stating: Your search encountered an error. If the problem persists, contact the portal site administrator.
My content is being indexed and I can get results with the default page ... see error message below:
First, you can try to access that page through /_layouts/viewscopesettingsssp.aspx?mode=ssp&scope=<x>. The <x> is a scope ID, you can assign it as 0 or 1 etc.
Then please check if there is any duplicate entries at the level of Display groups. If the duplicate entries is exist, you can try to remove the site collection which caused the duplicate entries.
