Problem: Error 633: the modem (or other connecting device) is already in use or is not configured correctly.

While I am connected to internet using Reliance Netconnect Huawei 1260, the connection disconnects after 10 to 15 minutes. Shows as connected Netconnect but does not work. I try to disconnect the connection, but it gives an error.

Reconnect to always remove the modem and then re - login again.

Please provede me a permanent solution to this. I use Windows 7 Enterprise

Hello

1. If it works well before?

2. what version of Modem drivers do you use? Do you have any other device connected to the computer?

First of all, I suggest you to check if the modem is compatible with Windows 7.

Check out the link:

Windows 7 Compatibility Center:

http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/default.aspx

I would also recommend to connect the modem to a different computer and check if it detects there. If it does not work on another computer also, then the problem is with the modem and I would ask you to contact the manufacturer of the modem for any further assistance.

Error 633 indicates that the port is already in use or is not configured for remote access dial out. You may need to check if the VPN and the connection connection try to use the same port that is causing the problem. You may need to check the settings of the modem and change the port for your needs.

To work around this problem, use one of the following methods:

Method 1:

Reserves explicitly the TCP port that is used for the VPN connection. To do this, follow these steps:

a. click Start, click run, type regedit.exe in the Open box and then click OK.

b. in the registry editor, find and then click the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters

(c) in the Edit menu, point tonewand then click multi-string value.

d. rename the multi-string value as 'ReservedPorts' and then double-clickReservedPorts.

e. in the value data box, type1723-1723, and then click OK.

f. exit the registry editor.

Registry warning: this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs.

.

Method 2:

Use the netstat command to find the program that is using port 1723. Then, end the process for this program. To do this, follow these steps:

a. click Start, click run, type cmd.exe in the Open box and then click OK.

b. at the command prompt, type the following command and press ENTER:

NETSTAT - aon

c. in the result which appears, identify the process ID for the program, if any, who is using the TCP port 1723.

d. at the command prompt, type the following command and press ENTER:taskkill/pid PID/f

Note: The taskkill command terminates the process that corresponds to the ID of the process. The/F option is used forcefully to complete the process.

e. at the command prompt, typeexitand press ENTER to quit the command prompt.

Restart your computer. This may cause the program that uses the TCP 1723 port to use a different port.

I hope that helps!
