Last reviewed: October 30, 1997

Article ID: Q142598

The information in this article applies to:


 * The Microsoft Network versions 1.05, 1.2, 1.3

SYMPTOMS
After you run the Internet Setup Wizard, you may receive the following error message when you try to sign on to MSN, The Microsoft Network, and the Internet:

Session Management Module is invalid.

CAUSE
Some computer manufacturers have placed the Internet icon on the desktop, but have not included Internet software on the computer. When you run the Internet Setup Wizard, it corrupts the MSN software.

Also, problems with Windows 95 Dial-Up Networking can cause this error.

RESOLUTION
Remove and reinstall MSN using these steps:


 * 1) In Control Panel, double-click Add/Remove Programs.
 * 2) On the Windows Setup tab, click the MSN check box to clear it.
 * 3) Click OK.
 * 4) In Control Panel, double-click Add/Remove Programs.
 * 5) On the Windows Setup tab, click the MSN check box to select it.
 * 6) Click OK.

To install Internet access, sign on to MSN and download the Internet software from Categories\MSN Classic Categories\Internet Center\Classic Internet Center\Getting On The Internet. If the Internet Setup Wizard does not run automatically upon completion of the download, run the wizard. This installs the necessary files for Internet access on the computer and configures the Transmission Control Protocol/Internet Protocol (TCP/IP) required for access.

After you restart the computer, you have Internet access.

If this does not resolve the issue, you must remove and reinstall Dial-Up Networking. To do so, use the following steps:

 Click Start, point to Programs, point to Accessories, and then click Dial-Up Networking. Right-click an MSN connection, and then click Delete. Repeat this step until all MSN connections are deleted. Close the Dial-Up Networking window. Click Start, point to Find, and then click Files or Folders. In the Named box, type "pppmac.vxd" (without quotation marks), and then click Find Now.
