| Description | An error was encountered while receiving a fax. Please wait a minute and have the sender try again. If difficulties persist, please check that the following items are working: Phone line, Sending Fax Device, and Receiving Fax Device. If problems persist, contact product support. |
| Event Information | CAUSE: This problem can occur because the fax server utilizes a T30 protocol for transmitting and receiving faxes. The T30 protocol is extremely time sensitive, and has several hard coded time-out values. If the fax threads that operate the T30 protocol do not run within a certain time period, the incoming fax may not be received, and may generate a timeout error message. Microsoft Windows NT Server is not a real-time operating system. There is no way to guarantee that a thread will run within a specified time slice. The fax threads may be preempted by other threads running on the computer and cause a timeout failure on the received fax. RESOLUTION: To try to work around this problem, increase the performance of the server by increasing the CPU speed or by off-loading some of the server services and functions to other computers or servers. STATUS: Microsoft has confirmed that this is a problem in BackOffice Small Business Server. |
