There is alot of factors that could be taking play here, but first things first, make sure it is not on your end. Alot of Router firmwares will make changes to the Registry (as I found out with DD-WRT, lmao)

DL this, (or use the Netstat command if you wanna make things complicated):

http://www.microsoft.com/downloads/deta ... laylang=en

They don't tell you this for some reason, but after DLing, unzip to default (maindrive), open folder, move PortQry.exe to Windows/System32 folder.

after that,
Start, run, CMD and enter this into the dos prompt:

portqry -local -l C:\Processes.txt -v

(replace ur main drives letter if it's not C:\Processes.txt)

This will generate a log file in your main drive where Windows, Program files is etc. that will tell you all the information you could ever want to know about your TCP/IP properties

Open the log with Wordpad. If it the info appears out of line, make sure under the format tab that wordwrap is checked. Also, you may need to go to font and set it to "Terminal"

Look for the following first (Hint: go to edit, Find.. then Copy paste the Process ID's, or port #'s) :

Scroll down a few lines to:

TCP/UDP Port to Process Mappings

First, check this out:

4:System TCP 445 0.0.0.0 LISTENING 0.0.0.0:28721
4:System TCP 139 192.168.2.2 LISTENING 0.0.0.0:32778
4:System UDP 445 0.0.0.0 *:*
4:System UDP 137 192.168.2.2 *:*
4:System UDP 138 192.168.2.2 *:*

-This happens to be my current config (as an example), yours will look ALOT different since you're not behind a router. Major players to note here are TCP/UDP ports 137-139 (netbios) in which at least one should be LISTENING or ESTABLISHED.


Also check the following Process ID (Essential for Outlook exchange):

Process ID: 1088

Service Name: RpcSs
Display Name: Remote Procedure Call (RPC)
Service Type: runs in its own process

PID Port Local IP State Remote IP:Port
1088 TCP 135 0.0.0.0 LISTENING 0.0.0.0:0

Port Statistics

TCP mappings: 1
UDP mappings: 0

TCP ports in a LISTENING state: 1 = 100.00%

For any and ALL of the required ports and configs for everything (and more, including required port assignments for Outlook):


http://support.microsoft.com/kb/832017#5

If you wanna mess around some more, type portqry /? in the dos prompt.

The portquery tool will aid you with Port # assignments to specific programs, but if it takes longer than 20 mins or so to find a problem, call your ISP and have them run a end-to-end mapping to find the problem. Don't waste your time lol.

Also, I'm not sure how far along Europes IPv6 structure is, but if you type ipconfig /all in the dos prompt and have a hexadecimal IP address (i.e fe80::5efe:192.168.2.2%2), then you should see 3-4 other interfaces below your ethernet card:

Tunnel adapter Teredo Tunneling Pseudo-Interface:

Tunnel adapter Automatic Tunneling Pseudo-Interface:

Tunnel adapter 6to4 Tunneling Pseudo Interface:

All of these are very important if your ISP supports IPv6 and IPv6to4

To install IPv6 go to Dos prompt. Type netsh ....wait..once in netsh mode type interface ipv6. Then type install. Reboot


Hope you can find the problem..

Forgot to mention another key debugging device that surprisingly nobody uses.

Start->Control Panel->Adminstrative Tools->Event Viewer

Open the system log and look for any errors or warnings. If none, open Application and check. If none there, you can enable security audits in Administrative Tools->Local Security Policy. Once in MMC expand Local Policy->Audit Policy. Double click each one and check Failure (only!).

Now the security log in event viewer will display any and all errors with detailed info and help links.

Thnx for ur support !!

But, problem is solved !
Turned out my ISP was blocking port 25
I was able to telnet to any mailserver but just not mine.

I shut down modem and kept it offline for 24 hrs.
Ran IPCONFIG /RELEASE on the comp and shut that down as well.

Went to a BBQ and drank some beer , couldnt drive anymore, stayed the night over

Got home this afternoon. Putted some power on the modem again, and thank god it gave me a new ip .
Sending and recieving mail was no problem anymore (cant explain in a few words how happy i was).

Crappy servicedesk . Gonna write them a complaint letter. I want my expensive calls to them refunded.

Since my router was broken i had to connect through modem directly. Thats why i couldnt change the routers MAC adress to get a new IP.

Thanks again for thinking with me !

Glad to hear!

Problems like this can be a pain sometimes.

BTW, in the future (and if your NIC supports it, most do) you can clone your MAC w/o a router by going into the TCP/IP properties of your adapter and hit Configure. Look for an option that says network address. You can change it there, but be careful and only change the last digit (ie. 00:03:25:3E:44:C1 (C2)). ur modem needs to be off when you do this, and then reboot. Plug modem back in, and you get a new IP.

[wever.nl-(DOG)-]

Yeah i know...especially when ISP keeps saying it aint their problem

And yes, i got the same advice for that mac cloning thingy.
When i get my new router, i'll see if thatss possible on that one.

Thanks again Louis !

This is not a criticism just an observation.

If you use an ISPs email you are tied in - when you leave you have to tell every one - or move the email to another host - if you own the domain.

I gave up "a long time ago" with ISP email and always use a public provider. I use: yahoo, google, and hotmail.

All of which allow forwarding and also support POP and IMAP - so even if you want to read/send via your ISP - you dont need to use them directly - they just hold a copy of forwarded mails from other systems. And you can add all sorts of forwarding/filtering rules....

(dont for get you can set the reply to address to anything you want mean anything : SMTP is an open protocol(so you can have some fun with it)) etc...)
