Hi, I've problem with share of Firefox/Thunderbird profile users. This profiles are locate in the personnal share of users (share on a ad member server). After several hours or minutes, all https connections are impossible. In the Event Viewer I can see : - mrxsmb error - Event ID 139 : Not all Files for the File \share\Firefox_or_thunderbird\profile\files.sqlite-shm could be saved. Some Data get losed. - Mup error Event ID 139 : Windows was unable to save all the data for the file \share\Firefox_or_thunderbird\profile\files.sqlite-shm the data has been lost. Some people have resolved the problem by disabling TCP Offloading. But It doesn't works for me. Does somebody have an idea ?
