Last reviewed: October 7, 1997
Article ID: Q131193
The information in this article applies to:
  • The Microsoft Network versions 1.0, 1.2, 1.3, 2.0, 2.5

SYMPTOMS

When you attempt to connect to The Microsoft Network, you hear a carrier tone but after 15 or 30 seconds the modem may lose the connection.

CAUSE

The S7 register, which controls the amount of time the modem waits for a carrier, probably does not have a sufficient value for the modem to recognize a compatible carrier issued by the remote modem.

RESOLUTION

Set the S7 register to a value of at least 60. To do so, follow these steps:

  1. Click Start, point to Settings, and then click Control Panel.

  2. Double-click Modems.

  3. Click Properties.

  4. Click the Connection tab.

  5. Click the "Cancel the call if not connected within" check box to select it, and then type "60" (without quotation marks) in the Secs box.

  6. Click OK or Close until you return to Control Panel.
