So, I will await the next step from you.

The standard ethernet MTU is 1500; PPPoE is 1492.
Information from MVP Steve Winograd:
This is a common problem with shared DSL connections that use PPP Over
Ethernet (PPPoE). Here are some possible fixes. Any one of them
should solve the problem:
1. Install Windows XP Service Pack 1 or 2 on the ICS host computer.
2. Find the right MTU setting on the client computer, as shown here:
and then make the setting manually on the client computer, or use
DrTCP to make it:
3. Download the free RASPPPoE program and install it on the host
computer. Use it instead of XP's PPPoE program. Details at these
See these sites for more information:

p.s. I believe I did a MTU check back with Ztruker (maybe just before ) and I am sure my machine is set at 1492. Also, some of the stuff we are doing now is going a little over my head so may need a bit of coaching.

Go to the run command window, type cmd, and press Enter. Now you can type in the commands and the window won't disappear.
If this happened, it didn't happen in this thread, because there is no reference to it in any of the previous posts. I'd suggest you make sure.

Yep, just ask when you have a question.

The computer with the problems (Microsoft sites access) is MY desktop machine and is the host computer......the fix you are advising appears to be for a 'client' computer which is having trouble accessing certain websites, which my wife's laptop is NOT experiencing. How should I proceed??
p.s. My wife is a Webmaster (but it is me in my best and limited way who keeps the internet connections and the computers/hardware running) who spotted the anomaly with the MTU config.

You can analyze your TCP/IP settings with the following:

Other anomalies on MY host machine (now that I have done the TCP/Ip test)are the fact that whenever I reconfigure my program defaults, for some reason thay do not stay changed to what I want.....several times recently I have re-set IE7 as default browser (and other settings also)but I see Firefox (which I have as backup) is now the listed browser, not only that but I see "Web fun Products" appearing in the browser listings, which I thpought I had cleaned out many months ago.
SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = 18.104.22.168 (22.214.171.124)
Browser/OS = Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; FunWebProducts; (R1 1.3); .NET CLR 1.1.4322; .NET CLR 2.0.50727)
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405ac0103030201010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
Default TCP Receive Window (RWIN) = 257004
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 64251
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 10280 kbps (1285 KBytes/s) @ 200ms
Your TCP Window limits you to: 4112 kbps (514 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 44 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

I suggest you go to the Malware Forum and run all the steps located in the START HERE. These self-help tools will help you clean up 70% of problems on your own. If you are still having problems after doing the steps, then please post a HiJackThis Log in THAT forum. If you are unable to run and/or post a HJT log, then post that in your initial post in the topic you create in that forum.
If you are still having problems after being given a clean bill of health from the malware expert, then please return to THIS thread and we will pursue other options to help you solve your current problem(s).

I must say, that I have recently been infected with a Trjan and had to do a complete scan with sys restore shut off (Avast, Uniblue , Ad-aware and Spyhunter used) but I thought my machine was cleaned.....maybe something got into the machine a bit earlier.
