Solve Network Problems #1 - No Workgroup PC

If you can see your workgroup PCs in MY Network Places, then you have a problem:

Update: 4/2/08

Every PC on your network might be acting as the MASTER BROWSER
Best to turn off feature:

If you open notepad and type the following in or copy and paste below:



To make on system act as the not the master browser..

Save as.. NoMasterBrowser.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters]
"IsDomainMaster"="FALSE"
"MaintainServerList"="No"

Next Now click on start then on run type: services.msc

Computer Browser Service: Not Started / Automatic
Network Connections: Started / Automatic



To make on system act as the master browser..

Save as..YesMasterBroswer.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters]
"IsDomainMaster"="TRUE"
"MaintainServerList"="Yes"

Next Now click on start then on run type: services.msc

Computer Browser Service: Started / Automatic
Network Connections: Started / Automatic



Do this on all PCs in your network..
Also do not use simple file sharing method make sure that box is uncheck on all PCs on your network. In my case 8 had to be re-done. It's not the router or switches it is one or two PCs are the network acting up..

There is a free tool from Microsoft called Browstat.exe:

Browstat status would tell you the condition of your workgroup or Browstat sta
When I first ran this program without using the script above I got errors so some PCs on the network were acting like the Master Browser.


Additional To fix..

Under My Network Places
Set up a home or small office network
Make sure your workgroup matches what's in there
and continue to run..

Next do the following...

click on start
click on run
type: cmd

type: ipconfig /flushdns
type: netstat -r
type: netsh interface ip delete arpcache

Now go to your Network Connections
Right click on your LAN or WLAN
Click on Properties
Click on Internet TCP/IP
Click on Advance

Default Gateway should have your DG (router)
If not put the IP in there and leave the Metric alone.
Click on the Wins tab
Change Default NetBIOS
To Enable NetBIOS over TCP/IP

Click apply or okay

Now...

click on start
click on run
type: services.msc

Make sure.. Computer Browsing is Enable and Started (auto)
Make sure... Network Connections is Enabled and Started (auto)

If you want your Router to show up under My Network Places under XP like it does Under Vista

You need to make sure SSDP is enabled and started (auto)
You need to make sure UPnP is enabled and started (auto)

In your router turn on UPnP (some of you say it slows down your connections, but I don't see that happening..

Now under My Network Places there is:

Show UPnP Devices click on that.. If you get an error, then you need to rebuild the dbase.

Fix is here:

Click on start
click on run
type: esentutl /p %windir%\security\database\secedit.sdb

This should this problem..

Wireless Bridge Drop with Hauppauge MediaMVP

Network Tweaks #3

Shows DRTCP, TCP Optimizer and a third TCP tweak program to improve networking preformance in TCP, Internet Browsing, LAN, WAN and DNSCache.

Network Problems #2 - Errors with ipconfig /flushdns

If you use ipconfig /flushdns and get an error:

Could not flush the DNS Resolver Cache: Function failed during execution.

This means

DNS client service is not running

To Fix:

click on start
click on run
type: cmd

Type the following as you see it:

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\Dnscache /V Start /T REG_DWORD /F /D 2

Press enter and wait for the message that said OK

Exit out an then exit out of Windows..
After the reboot login to Windows..

click on start
click on run
type: cmd

type: ipconfig /flushdns

It should work now..
