Wireless ActiveSync Attempt results in Error 0x80072EE2 in ActiveSync

Workaround:
Disable the Windows Mobile DNS cache. This requires a registry
modification. Windows Mobile does not include a registry editor, but
free third-party editors are available (such as one from www.phm.lu).

Change the value of:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\InternetSettings\DnsCacheEnable
to 0
If DnsCacheEnable does not exist, create it as a DWORD value.

A soft reset is necessary for the change to take effect.
