Logical ORing SQL LIKES

I've been happily using the following select statement to return values from a table:

SELECT DISTINCT AliasValue FROM GAS_Aliases2ThemeItems1 WHERE AliasValue LIKE  '%OPCServer\SmarOleServer%'  ORDER BY AliasValue

Then someone put a record in the table with an AliasValue containing OPCServer\OACServer, and I'm supposed return this record in addition to the ones above. No problem! I'll just "OR" the LIKES into something resembling

SELECT DISTINCT AliasValue FROM GAS_Aliases2ThemeItems1 WHERE AliasValue LIKE '%OPCServer\SmarOleServer%' OR '%OPCServer\OACServer%' ORDER BY AliasValue

But this returns all the distinct values in the table. So what happens if we group the LIKE into

SELECT DISTINCT AliasValue FROM GAS_Aliases2ThemeItems1 WHERE AliasValue LIKE ('%OPCServer\SmarOleServer%' OR '%OPCServer\OACServer%') ORDER BY AliasValue

This return a null recordset.

Each "LIKE" individually returns the values expected.

I'm OBVIOUSLY missing something in the LIKE wildcarding syntax.

What should the Select statement look like?

ps: I've upped the point count so I can reward someone who can EXPLAIN this, not just the what.
