I'm posting my success with having the contents of searchable PDF files in my WHS 2011 shared folders appear in client Windows Search results. Here are the steps I took on the server after RDPing. YMMV and be sure to take the proper precautions (backup,
etc.).
1. Download and install Adobe's PDF iFilter 9 for 64-bit platforms from
http://www.adobe.com/support/downloads/detail.jsp?ftpID=5542
2. Start Regedit and go to HKEY_CLASSES_ROOT\.pdf\PersistentHandler. Verify that the value is 1AA9BF05-9A97-48c1-BA28-D9DCE795E93C. If an Adobe Acrobat or Reader install overwrote the entry with F6594A6D-D57F-4EFD-B2C3-DCD9779E382E, return it to its original
value.
3. Go to Control Panel - Administrative Tools - Services. Find Windows Search. Right-click, and then choose Restart.
4. Go to Control Panel - Indexing Options - Advanced button - File Types tab. Scroll down to pdf and verify that it shows 'Reader Search Handler'.
5. Still in Advanced Options, click the Index Settings tab and click Rebuild. That will take some time but if you don't rebuild, only new pdf files will get indexed.
