I have a shared folder on my Server2008 SBS server that contains about 150,000 .pdf and .txt files. We have a problem with the initial access of any file in that folder. It takes from 4 to 6 minutes to open that initial file. After the first file has been opened, subsequent files open in 3 to 5 seconds. Performance remains good for the rest of the day, but after the computers are shut down at the end of the day and restarted the next morning that initial file access reverts back to 4 to 6 minutes.
I have turned off indexing on that folder but it didn't help.
I have also set the "Allow only per user or approved shell extensions" to "Enabled" in the GPO. Again, no apparent change.
Please help! I am at a loss.
