SYMPTOMS
Groove Virtual Office and Groove Workspace communications that use port 80 are unsuccessful on a computer that is running InterMute or a default configuration of AdSubtract. When this behavior occurs, some or all workspace data may not synchronize. Additionally, messages to some or all contacts may not reach their recipients.



CAUSE
InterMute, an obsolete browser filtering program from the InterMute company, is designed to selectively filter ads, cookies, pop-up windows, Java and JScript, and so on. If Groove is using a port 80 connection for all traffic or for some traffic, InterMute prevents operations that Groove requires.

InterMute has replaced the InterMute program with AdSubtract. AdSubtract is a more sophisticated browser filtering program. The default configuration of AdSubtract causes the program to interfere with Groove. However, AdSubtract can be configured to allow Groove communications.



WORKAROUND
To use Groove together with AdSubtract, you must define the Groove relay servers as custom sites. Then, you must selectively disable filtering to those custom sites. For information about how to do this, see the InterMute article &quot;When I click a link, game or applet it does not open. Why?&quot; To view this article, visit the following InterMute Web site:
