SBS RWW ActiveX Control Error

A problem discovered by another technician for a client which  points to a possible problem with clients which use RWW to connect to their desktop computer at the office who are running Windows XP SP-3 with IE8 installed. The symptom is that when they click to see a list of computers that they can connect to, they see:

“This portion of the Remote Web Workplace requires the Microsoft
Remote Desktop ActiveX Control. Your browser’s security settings may
be preventing you from downloading ActiveX controls. Adjust these
settings and try to connect again.”

Be sure to check the following:

  • IE Compatibility Mode is enabled for the RWW site
  • The site is on the “trusted site” list
  • From the command line, type “regsvr32 mstscax.dll” to re-register the control
