14 DAY TRIAL // Customers running Windows 7 RTM and Windows 7 Service Pack 1 (SP1) can have issues establishing a dial-up connection after they wake their computers from sleep or hibernation.
Microsoft has officially confirmed the issue, and published KB 2618301, offering additional details to users impacted by this problem.
According to the software giant, in addition to Windows 7 RTM and SP1, Windows Server 2008 R2 RTM and SP1 are also affected.
Here is how Microsoft describes the symptoms encountered by customers:
“When you resume a computer that is running Windows 7 or Windows Server 2008 R2 from sleep or from hibernation, you cannot establish a dial-up connection through a modem.
Additionally, you may receive the following error message: Error 633: The modem (or other connecting device) is already in use or is not configured properly.”
There’s a simple fix to take care of this issue, but it’s a temporary solution. Customers can restart their computers as a workaround. Alternatively, they can reset the modem they’re using before trying to establish the dial-up connection.
The Redmond company already identified the source of the problem, explaining that:
“This issue occurs because a flag is not reset after the device state is cleaned up when the computer is put to sleep or into hibernation. Therefore, the flag is in an inconsistent state when you resume the computer.
The flag is set when the computer is put to sleep or into hibernation. The flag indicates that the states of various internal structures for the modem device have to be cleaned up.”
An update designed to resolve the problem described in this article is already available from Microsoft.
