- Introduction
- ============
-
- This latest version of the TweakDUN utility offers the user a number
- of useful functions... the ability to change various Windows Registry
- settings to enhance data transfer rates. The registered version also
- includes an MTU Search which can aid in determining the MTU setting
- between you and your local provider. It also permits the user
- to configure a local hosts file to speed up Domain Name searches.
- The registered version of TweakDUN also features an Internet Update
- feature which will automatically find out if an updated version
- is available, download it and install it. The above features are all
- explained in the Helpfile which installs with the program.
-
- New with v2.2 was full support for AOL 3.x and 4.x in Windows 95/98.
- A MaxMTU of 1500 is "hardcoded" into the AOL software. TweakDUN employs
- a unique algorithm to successfully change the MaxMTU setting and permit
- AOL users to realize the same faster download speeds enjoyed by other
- Internet users. The latest version new support Microsoft Dial-Up
- Networking (DUN) 1.3.
-
- TweakDUN allows you to automatically change certain Windows default
- settings including MaxMTU (Maximum Transmission Unit), RWIN (TCP Rcv
- WINdow) and TTL (Time To Live). Basically, these are settings which
- can help prevent fragmentation in data transfer using the TCP/IP
- protocols used on the Internet, and greatly increase modem
- throughput. In addition, you can also make changes to PMTU Auto
- Detect, PMTU Black Hole Detect, and Session Keep Alive. This is all
- explained in greater detail in the TweakDUN helpfile.
-
- TweakDUN is a foolproof method to change these settings easily and
- quickly. The installation creates a TweakDUN folder under the Programs
- Menu. Launch the application, change your MaxMTU or other related
- settings, and it will prompt you to reboot your computer in order for
- the new settings to take effect. TweakDUN includes full support for
- all language versions of Windows 95/98/NT4.
-
- Note: Some people have had good success after only changing MaxMTU.
- But for maximum efficiency it is advisable to make an entry for RWIN,
- and in many cases TTL as well. Many people have reported much better
- data transfer rates *only* after making these additional settings.
- In order to change these additional settings, it is necessary to
- register TweakDUN. The evaluation version of TweakDUN will show
- certain settings greyed out.
-

-
- Backing up the Registry
- =======================
-
- ***IMPORTANT*** TweakDUN involves making changes to your registry.
-
- Whenever registry changes are made, it is ALWAYS advisable to backup
- your registry first. Use a software application such as the Win95
- utility ERU or the manual method described at the NetPro NorthWest
- website at:
- http://www.infinisource.com/restore.htm
-
-

-
-
-
- Installation
- ============
-
- PLEASE READ CAREFULLY!!!
-
- TweakDUN is written in Visual Basic 5, a popular programming language.
- It requires the latest Service Pack 3 (SP3) Visual Basic Support files.
-
- The STANDARD Installation for TweakDUN should be run while connected
- to your Internet Service Provider. The installation will then check your
- system for the necessary Visual Basic files and install only the ones
- needed to your Windows\System directory.
-
- A FULL installation version of TweakDUN containing the entire VB5
- Service Pack 3 is also available at the TweakDUN website at:
- http://www.pattersondesigns.com/tweakdun/tdweb/td_22s_vb.exe
-
- If you wish, you can also run the STANDARD install offline and download
- the entire VB5 package separately.
-
- Download locations for the VB5 self installing exe are listed at:
-
- http://www.pattersondesigns.com/tweakdun/vb5.htm
-
- These VB5 Runtimes need to be installed *BEFORE* you try to
- run Tweakdun. Just doubleclick on the self-installing VB5 file
- to update/install. The install contains, in most cases, the latest
- versions of these DLL's available which, according to Microsoft,
- are fully backwards compatible... that is, any program which works
- with an earlier version, should work with these updated ones as well.
- The updates simply give the programmer more advanced features to use
- in designing his program. This will update the following dll's in
- c:\windows\system.
-
- Asycfilt.dll
- Comcat.dll
- Ctl3d.dll
- Msvbvm50.dll
- Oleaut32.dll
- Olepro32.dll
- Comdlg32.ocx
- Stdole2.tlb
-
- NOTE: If you are running Windows 98, the VB5 Runtimes do not need to
- be installed. They are included with Win98. Also if you have a later
- version of any of these dll's, the separate VB5 installation process
- will alert you to that fact and recommend you keep the one you have,
- which is always advisable. If it locates an older version it will
- prompt you to download the newer one to update your system.
-
- ALSO: you may have been prompted to reboot during the runtimes
- installation process and required to run the installation a second
- time after your system reboots. This is often necessary to update
- the ole automation dll files that may be in use at the time.
-
- TO INSTALL TweakDUN it is not necessary to first uninstall any
- previous versions of TweakDUN, registered or unregistered. This new
- version will overwrite any previous installations if installed to
- the standard Program Files\TweakDUN folder. The TweakDUN installation
- will install the following files to your hard drive in the TweakDUN
- directory:
-
- Tweakdun.exe
- Tweakdun.hlp
- Tweakdun.cnt
- Sample.twk
- Tdupdate.exe
-
- These files will be installed to your windows\system directory:
- comdlg32.ocx
- msinet.ocx
-
-
- Uninstallation
- ==============
-
- There is no uninstallation for the Visual Basic Runtime files.
- This should not be needed however, since they are all Microsoft
- files which are supposed to be all fully backwards compatible.
- If you wish to take added precautions read the readme file included
- with the VB5 files and make backup copies of the original VB5 dll's
- present on your system before you perform the upgrade.
-
- TweakDUN can easily be uninstalled. Note, however, that if you
- uninstall TweakDUN you can no longer use it to change the values,
- which will remain where they were last set by the program.
-
- To uninstall the program follow these steps:
-
- 1. Open Control Panel
- 2. Open Add/Remove Programs
- 3. Select TweakDUN and Click the Add/Remove button.
-
- Uninstall removes the all of the installed files listed above.

-
- Technical Support & Contact Information
- =======================================
-
- Please note that there are no guarantees that changing the MaxMTU,
- RWIN and other settings from the Windows 95 default will speed up
- your data transfer rates. There are too many variables to ensure
- the increase in every situation. Your particular ISP, phone lines,
- computer configuration and modem may limit the speed of your
- connection more severely than these settings.
-
- In addition, general Internet congestion, a slow web server or
- bottlenecks created by intermediary routers in any data transfer
- situation may preclude high speed transfers. Still, our feedback
- indicates that roughly 80-90% of people who experimented with these
- settings and filled out our online survey form had moderate to
- excellent success with changing these settings.
-
- Nevertheless... "Your actual results may vary."

-
- Known Bugs and Other Issues
- ===========================
-
- Note that TweakDUN 2.21 does not support importing of bookmarks from
- Netscape Communicator 4.5 which employs it's bookmarks differently
- than 4.0x. The next version will hopefully include that support.
-
- There are no known bugs at the time of release of v2.21. However,
- the following problems crop up occasionally:
-
- Occasionally, upon installation some people may receive a Windows
- error message: "This application uses CTL3D32.DLL which is not the
- correct version. This version of CTL3D32.DLL is designed only for
- Windows NT systems." There is no cause for alarm. TweakDUN does NOT
- install this dll file. This message simply indicates that you
- probably have the incorrect version of this dll in your
- windows\system folder. It should not cause you any problems, but if
- you wish to find out more, see the TweakDUN helpfile or the relevant
- section on the MaxMTU page at
- http://www.infinisource.com/maxmtu.htm#rwin
-
- On some systems, running TweakDUN's Find MaxMTU feature may produce
- this warning:
- "This program is set to run in MS-DOS mode
- and cannot run while other programs are running.
- All other programs will close if you choose to
- continue. Do you wish to continue"
- This error is produced by a default setting in the way a DOS window
- is opened on your computer. The procedure to correct this situation
- is outlined in TweakDUN's help file.
-
- If you are getting reports of Active-X errors, this is not caused by
- TweakDUN directly and is a known bug with MS Internet Explorer and
- ActiveX. You can read the article in the Microsoft Knowledge Base
- on this at
- http://support.microsoft.com/support/kb/articles/Q177/9/43.asp
- You can also write to us at support@pattersondesigns.com for a help
- file on how to handle this problem.
-
- Another occasional problem that occurs is this error message:
- "MSINET.OCX not correctly registered.
- File missing or invalid."
- Here again, this file should be installed by TweakDUN. If it is not,
- then the problem is most likely with one of the files MSINET.OCX
- depends on not being of a recent enough version. Here again we have
- a very thorough helpfile for you here at support@pattersondesigns.com
- if you encounter this problem.
