Multiple DNS Server Addresses Not Assigned Properly with DHCP

 * }

Q157930

-

The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
When you attempt to use multiple Dynamic Host Configuration Protocol (DHCP) servers to dynamically assign Domain Name Service (DNS) server addresses to multiple network adapters installed in your computer, the DNS server addresses may not be assigned properly.

CAUSE
You cannot manually assign different DNS server addresses to multiple network adapters in Windows 95. To assign different DNS server addresses to multiple network adapters, you must use DHCP servers. If each network adapter is connected to a network that contains a DHCP server, the DHCP servers can be used to dynamically assign DNS server addresses to each network adapter. However, the Wsock32.dll file included with Windows 95 does not properly implement this feature.

RESOLUTION
This issue is resolved by the following updated file for Windows 95, and later versions of this file:

  WSOCK32.DLL  version 4.00.952  dated 9/26/96  67,072 bytes A version of this file which resolves this problem is included in the Windows Sockets 2.0 update for Windows 95. For information on obtaining this update, see the following article in the Microsoft Knowledge Base:

"Q182108 Availability of Windows Sockets 2.0 for Windows 95"

STATUS

An update to address this problem is now available, but is not fully regression tested and should be applied only to computers experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft does not recommend implementing this update at this time. Contact Microsoft Technical Support for additional information about the availability of this update.

This issue is resolved in Microsoft Windows 98.
