Back ground.

Equipment used

Farmside (satalite broadband) with there equipment
Router with wan output to connect to the satalite pppoe set correctly with user name etc and set to auto dial

Wireless access point to send wireless signal to all parts of the buisness

problem

Windows vista basic

toshiba laptop

will connect wirelessly to the access point but drops the signal. (laptop sitting right next to the access point 100% signal strength)

To try and solve the dropping of connection i updated the wirless drivers no differnce

so i decided to put on via ethernet cable to elimnate this problem.

when i try to do so i get the following message (keepin in mind 10 xp machines connect via the same method and 1 vista)

security policy settings on this computer might be blocking the connection

policy provider

filter name, query user

so i shut the fire wall off and somtimes connects and somtimes doesnt. as they are a buisness this is not suitable to have the fire wall disabled. the network is set to private so that all connections can be made and established.

with the fire wall off 99% of the time i get this message

there maby a problem with your domain name server

windows found a problem that can not be repaired automaticly.

after spending an hour trying to get th ething to wwork. i take it back to my office to see if it would connect to our broad band. works perfectly on wireless and ethernet cable.

why would it not work at the clients site? 10 other pc's have the same set up.

im thinking the fire wall has become corrupt somehow? i ran norton removal tool on it just to be sure but did not fix the problem

does any body have any ideas?

note: all ip and dns etc are set to automatic and i did try to manually set them but made no difference.

i know many people are having similar problems on google but not clear answer to what should be done about this

please help and thankyou in advance.

Hu? did i do that?

Ouch. looks like you have a bad case of network fever. Do you have a server such as Windows Server 2003 or Windows SQL or anything like that. because if you do then it would be a setting in your firewall, or it could be the bandwidth of the network router (too many users on at once).

If you don't have a server. you should get one. easier to manage networks.

No server. i dont think it would be this problem otherwise i would be having problems with the other computers.

Its a clients computer and a server is not an option. i think its isolated to this one vista machine. somthing to do with the fire wall or a corupt policy or somthing i have googled the problem a few other people have had the same issue only running a direct cable from adsl modem to laptop. nobody has given a clear indercation of what it could be. i spent most of today trying to sort this issue out. so it sounds like a vista issue rather than a networking issue involving the router its self. seems that because i connected to a differnt network with no problems there is a problem iwth the profile on this one network. but i have removed them and started again didnot fix :(

If this machine is not yours and belongs to a client it's quite possible his network administrator set a security policy that allows only some connections, gateways or other features - may not be related to firewall at all.

If this is the case you will have to ask the administrator to remove or change the policy.

We handle all of their it equipment. they do not have an IT department on site. its realy a prety simple setup every thing works fine its just this one computer.

may have made it sound more complicated than what it is. but i was trying to give a full back ground.

basicly they are using a PPOE system through a gateway/router that allows them all to use the PPPOE. they are not sharing files or need a complicated setup. they are simply browsing the internet. but the internet is critical for what they do.

however thankyou for your comments

edit: no body would have done that unless by accident. and if so it would have been done on the local computer. if any ideas on how to clear that policy info please let me know.

When you talk about the firewall is this the Vista firewall or a third party firewall?

Also you mentioned a message about the domain. If you press the windows & break keys, it will bring up the System window. Under the computer name etc. section what does it have under workgroup?

Disconnect the Vista pc from router, go to Network and Sharing Centre > Windows Firewall > Allow Program through Windows Firewall > Advanced > Restore Defaults. Then go to Command Prompt and type "ipconfig /flushdns". Then go to Services and turn off DHCP client. Then go to Device Manager and uninstall and re-install the Network adapter. Then in Network and Sharing, make sure network discovery is turned on, and replug pc into router. If all goes well and Vista connects (with the new settings) you'll get an option to make it a Public or Private network. Choose Private. Then turn DHCP client back on.. It can also help if Vista pc has the same Workgroup name eg. MSHOME as the XP pc's. It sounds long and drawn out but should only take 5-10 minutes...

You could also try rebuilding winsock

   1. Click on Start button.
   2. Type Cmd in the Start Search text box (don't press enter yet).
   3. Press Ctrl-Shift-Enter to run Command Prompt as Administrator. Allow elevation request. (this assumes UAC hasn't been turned off)
   4. Type netsh winsock reset and then press the Enter key.
   5. Restart the computer.

What the netsh winsock reset command does is resets the Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed (eg: corrupt or third party layers).

Corrupt Winsock or Windows sockets configuration can be due to a lot of reasons such as installation of a networking software, or due to virus, trojan or malware infection, or sometime even due to disinfection of spyware by security software.

From memroy the work group is the name of the buisness. that was kinda strange but i didnt want to touch that or i would have to set up the shared network printer again. which was a pain in the first place thanks

Hu guys. Just an update after a gritty day sloging on this issue.

Change the workgroup as it was differnt to the rest of them. = no differnce

tried the suggestions above = no differnce

noticed that it did not have vista service pack 1 so i installed that and found some forums about a few ideas which i tried but have not had a chance to test as i ran out of time. if it works i will post links for what i did so any body else having this issue will know.

Note: i tried our company laptop that has vista premimum on it same results as the clients vista basic laptop.

so im thinking vista issue. will update on monday after i have tested my stuff i found. would have posted links. no point if it didnt fix it and i havent tried it yet so i will update.

thanks guys

When you tried your company laptop, were you using the same cable?
Have you tried a different cable?

trig 42: yes thanks trig. i tried a cable from a computer that was working on the network. i also tried the cable in a computer that was working on the network. so i have elimitated the cable issue. one of the first things i tried.

thanks for your suggestion.

lol. i know how many people have been caught out like that though its often the most obvious things :)

So the computers get an IP address from the DHCP server on the farmside router?
Have you tried manually entering DNS server addresses?
Can you ping a website by IP address (eg google.co.nz = 66.249.89.104),

You say they have 10 XP machines and one problematic Vista machine. I wonder if the router has a limited scope or can only handle 10 clients at a time (weird I know, but with a cable, Vista should just work)? Have you tried unplugging all the other machines and plugging the Vista machine directly into the router (unplug the switch from the router)

Hey trig. I have tried all of those suggestions. apart from pinging google. but the dhcp is done by the router rather than the farmside modem. the farmside modem only allows an interface between the the router and the satalite dish (pppoe) then the wireless router with WAN plugs into the farmside router and dials out. This way you can have more than one computer on PPPOE.

I have tried entering the dns that farmside use. and i also tried entering the dns of the router. nither worked. thanks for the suggestion

the research i did on firday suggested that the ipv6 was part of the problem and to turn off some services. also to enter a few things in the command line to turn other stuff on. i have done this but yet to test on the site router. will update you on monday how i get on with that.

I also noticed that it did not have service pack 1 on it so i installed that onfriday also. thats why i ran out of time because it takes a long time to install. thanks

Two things stand out...

1. "after spending an hour trying to get th ething to wwork. i take it back to my office to see if it would connect to our broad band. works perfectly on wireless and ethernet cable."

2. "Note: i tried our company laptop that has vista premimum on it same results as the clients vista basic laptop. "

I'm thinking the firmware on the clients routers might need updating. Both laptops seem to work on your router and not theirs. Try running a network protocol analyzer like Wireshark while your trying to connect the laptop to the clients router. It could show where the connection breaks down..

Cheers ;-)
