- The Remote Access Connection Manager service failed to start the RAS Async Adapter driver
(AsyncMac). The most common reasons for this error are:
- The RAS Async Adapter driver (AsyncMac) failed to initialize.
- The Remote Access Connection Manager service does not have sufficient permissions to open the driver.
- The Remote Access Connection Manager service failed to load rasser.dll.
- The modem has moved to an unsupported BPS rate.
- The serial driver could not allocate adequate I/O queues.

- Check whether the System account has read/execute permissions for the file
%systemroot%\system32\drivers\asyncmac.sys. To check the permissions:
- Right-click the file name, and then click Properties.
- On the Securities tab, verify that the System account read/execute permissions for the file.
- Verify whether the file rasser.dll exists at %systemroot%\system32 folder.
- Verify whether the System account has read/execute permissions for rasser.dll.
To check whether the System account has these permissions:
- Right-click rastapi.dll, and click Properties.
- On the Security tab, verify whether the System account has read/execute permissions for rastapi.dll. If it does not, add them.
- Move the modem to a supported BPS rate.
- Stop and restart the Routing and Remote Access service.
- If the problem persists, you might need to repair or reinstall the Windows operating
system
