------------------------------------------------------------------------- Microsoft TCP/IP-32 version 3.11b ------------------------------------------------------------------------- 1.0 Introduction 2.0 Installation Instructions for TCP/IP-32 version 3.11b 2.1 List of Bugs Fixed in TCP/IP-32 3.11b 2.2 Descriptions of Bugs Fixed in TCP/IP-32 3.11b 3.0 More Information 1.0 Introduction ----------------- The Microsoft TCP/IP-32 version 3.11b is the latest update to the TCP/IP-32 stack for Windows for Workgroups 3.11. It has been updated since version 3.11a and includes a number of fixes, primarily to provide compatibility with several third-party WinSock applications, and to correct problems with using DNS to resolve NetBIOS names. This also has updated code related to Windows 95. This update is a complete refresh of TCP/IP-32 and contains all components of the product. This product is compatible with and supported exclusively on Windows for Workgroups version 3.11. If you are running a different TCP/IP product on your computer, you must remove it before installing Microsoft TCP/IP-32. If you experience difficulties with another vendor's product, remove the existing TCP/IP stack, exit Network Setup completely, reboot your system, and then proceed to add the Microsoft TCP/IP-32 drivers by following the instructions given in the documentation. NOTE: When you upgrade to TCP/IP-32 3.11b, you should also update your Windows for Workgroups operating system with the files found in the \CLIENTS\WFW\UPDATE directory on the Windows NT Server version 3.51 CD-ROM or in the self-extracting file, WFWFILES.EXE. This update is necessary to logon to a Windows NT domain over routers when using TCP/IP-32b. For additional information on this update, please see the following article in the Microsoft Knowledge Base: ARTICLE-ID: Q133255 TITLE : README.TXT: Windows for Workgroups Update Files 2.0 Installation Instructions for TCP/IP-32 3.11b -------------------------------------------------- There are two ways you can install the TCP/IP-32 version 3.11b upgrade on your computer. You can completely reinstall your TCP/IP-32 network protocol stack with TCP/IP-32 3.11b, which will overwrite your previous TCP/IP settings with default settings. Alternatively, advanced users can manually copy just the updated binary files to the proper directories. This will retain your TCP/IP-32 settings, but will not update the TCP/IP-32 version number. Complete Reinstall: 1. From the Network group, choose the Network Setup icon. 2. Choose the Drivers button (Under Network Drivers, you will see your Network Interface Card (NIC) and the network protocols used on that NIC). 3. Select TCP/IP-32 3.11. 4. Choose the Setup button, review and write down all of your TCP/IP-32 configuration information. 5. Choose the Cancel button to return to the Network Drivers dialog box. 6. If TCP/IP-32 3.11 is your only network protocol, then temporarily add the NetBEUI network protocol by following these steps: A. Choose the Add Protocol button. B. Select Microsoft NetBEUI. C. Choose the OK button (Microsoft NetBEUI will appear under Network Drivers). 7. Select TCP/IP-32 3.11. 8. Choose the Remove button and then the Yes button to confirm. 9. Choose the Add Protocol button. 10. Select Unlisted or Updated Protocol and Choose the OK button. 11. In the Install Driver dialog box, enter the path to the updated TCP/IP-32 3.11b files (You should then see Microsoft TCP/IP-32 3.11b in the Unlisted or Updated Protocol dialog). 12. Choose the OK button (You should then see Microsoft TCP/IP-32 3.11b in the Network Drivers dialog box). 13. Choose the Setup button and configure TCP/IP-32 3.11b based on the information you wrote down in step 4. 14. If you added Microsoft NetBEUI as a network protocol in step 6 and do not want to keep it, select Microsoft NetBEUI, choose the Remove button and then the Yes button to confirm. 15. Choose the Close button to exit the Network Divers dialog box. 16. Choose the OK button to exit the Network Setup dialog box (Setup will modify system files). 17. Choose the OK button (Network Setup prompts you to reboot). 18. Choose the Restart Computer button (The TCP/IP-32 3.11b upgrade is now complete). Manual Installation for Advanced Users: 1. Copy the following files to the C:\ directory: NOTE: By default, the Windows root directory referred to above is C:\WINDOWS. If you installed Windows into a directory other than C:\WINDOWS, copy these files to that directory. 05/26/95 10:57a 60,551 ARP.EXE 05/26/95 10:57a 81,968 FTP.EXE 05/26/95 10:57a 42,195 IPCONFIG.EXE 05/26/95 10:57a 33,227 NBTSTAT.EXE 05/26/95 10:57a 69,465 NETSTAT.EXE 05/26/95 10:57a 58,307 PING.EXE 05/26/95 10:57a 57,703 ROUTE.EXE 05/26/95 10:57a 63,904 TCP32UI.DLL 05/26/95 10:57a 57,216 TELNET.EXE 05/26/95 10:57a 55,277 TRACERT.EXE 05/26/95 10:57a 41,440 WINSOCK.DLL 2.

Q121317: TCP/IP-32 version 3.11 Does Not Include Terminal Font Q120051: DNS Reverse Name Resolution Requests Are Incorrect Q120052: NBT Query Can Hang Computer or Drop Back To MS-DOS Q122293: LMHOSTS Lookup Can Cause Intermittent System Pauses Q119575: TCP/IP-32 Winsock Stops FD_READ Notification Q119918: Winsock: Accept() Sockets Are Unexpectedly Aborted Q125486: Ioctlsocket Function Returns Incorrect Data Q125437: Winsock calls return WSAEINPROGRESS Q121619: ARP Cache Commands May Not Work Correctly Q125963: IPCONFIG Shows Leftover DHCP Parameters On Non-DHCP Clients Q128725: Domain Name Ignored by Windows for Workgroups with TCP/IP-32 2.2 Description of Bugs Fixed in TCP/IP-32 3.11b ------------------------------------------------- TCP/IP-32 version 3.11 Does Not Include Terminal Font: Beta versions of Microsoft TCP/IP-32 included a font named "Terminal" in the Telnet application. This font is not included in the released version of the TCP/IP-32 Telnet application. DNS Reverse Name Resolution Requests Are Incorrect: TCP/IP-32 does not return the correct IP name when it queries the Domain Name Service (DNS) because it sends an improperly formatted query to the DNS. NBT Query Can Hang Computer or Drop Back To MS-DOS: Your computer running Windows for Workgroups version 3.11 with TCP/IP-32 network protocol stops responding (hangs) or drops back to MS-DOS when the 32-bit NetBIOS over TCP/IP (NBT) makes a query to the Domain Name Service (DNS). LMHOSTS Lookup Can Cause Intermittent System Pauses: Your computer running Windows for Workgroups version 3.11 with TCP/IP-32 intermittently stops responding (hangs) for about 20 seconds at a time. This occurs if TCP/IP-32 is installed as a non-default network protocol and the Enable LMHOSTS Lookup option in Network Setup is checked. TCP/IP-32 Winsock Stops FD_READ Notification: FD_READ notification in a Winsock application may stop while the application is running. This may cause data to be left in the input buffer, or, it may cause the application to hang. This occurs when the application disables and then re-enables FD_READ notification during a period of time while the Windows message queue is full. Winsock: Accept() Sockets Are Unexpectedly Aborted: Occasionally, when you execute a PUT command from an FTP client, your session to the FTP server is aborted. \* \* MSINTERNAL: \* Ioctlsocket Function Returns Incorrect Data \* \* If a second ioctlsocket() call is issued to the same socket after a \* recv() completes, number of bytes in the receive buffer returned from \* the ioctlsocket() is not getting updated. Winsock calls return WSAEINPROGRESS Windows Sockets applications running on Microsoft TCP/IP-32 may receive error 10036 (WSAEINPROGRESS). This problem occurs when applications process a large number of Windows Sockets calls. ARP Cache Commands May Not Work Correctly ARP -S commands may not function correctly under Microsoft TCP/IP-32 when the arp cache is empty. IPCONFIG Shows Leftover DHCP Parameters On Non-DHCP Clients If TCP/IP-32 client is configured to use DHCP and then re-configured it not to use DHCP, when the command "IPCONFIG /ALL" is executed, it will show old (DHCP supplied) values for certain parameters. Domain Name Ignored by Windows for Workgroups with TCP/IP-32 When a Dynamic Host Configuration Protocol(DHCP) client running TCP/IP-32 version 3.11 requests an IP address from a DHCP server, the IP address is received but the domain name is not recognized by the Windows for Workgroups client computer. 3.0 More Information -------------------- For known problems and various support options, please read README.TXT that accompanies Microsoft's TCP/IP-32 3.11b update.
