When using the steps to decrease latency described in http://www.mmowned.com/forums/wow-ex...g-forever.html some people do not have the MSMQ folder. The problem is installed, but you can't find the registry folder to complete the regedit.
I personally had this problem, and if you also do, follow these instructions. I had to manually create the folder, and these directions that I am supplying should provide you with the .reg file necessary to create the folder.
1. Open up Notepad.
2. Copy these EXACT lines into Notepad:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters]
"TCPNoDelay"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters\OCMsetup]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters\Security]
"SecureDSCommunication"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters\setup]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Setup]
Leave one extra blank line after the \Setup]
3. Now, click Save As..., save to the desktop, and save as "all files" (NOT .TXT). Save the file as msmq.reg and minimize to the desktop.
4. The file should look like a broken rubix cube. Double-click on it and it will ask if you want to merge it into the registry. Click yes.
Note that the TCP value is entered in the copy/paste, so you don't have to enter in the new values.
