adsl problem

[mdvl]

greetings,

my adsl problem:

I can login to ISP everytime (via winXP's PPPoE).

I can always access: hotmail.com, support.microsoft.com, msn.com, dummies.com, radioshack.ca, and yesterday learnt about accessing neowin.net (via InternetExplorer 6).

I cannot access any other websites, nor can i download emails from ISP (via OutlookExpress 6).

Rarely, like once a day, after logging in, everything is functional.

I can access all https, and able to download emails from ISP.

BUT!!! after approximately 5-60 minutes, back to only accessing the mentioned above websites.

I've tried:

-using RASPPPoE (same results).

-configuring TCP/IP 192.168.xxx.xxx,255.255.255.0 (same results)

-disabling/stopping DNScache (Administrative Tools/ Services/ DNSclient). i thought this was the fix yesterday because had "full" access for a few hours, BUT!!! once again back to only accessing those websites.

-tweaking MTU,TCP using DRTCP,RASPPPoE,TCPoptimizer (same results)

any other suggestions would be greatly appreciated.

strange enough, never had this problem with old PC (P166 on win95, using Enternet1.41, IE4.0 or IE5.0 cant remember).

Am currently using HP Pavillion 7935 PC (AMDathlon1.3 with pre-installed winXPhome).

:right:

are you just can not resolve domain names or you actualy can't ping anything?

[mdvl]

resolving domain names must be the problem.

i'm able to ping via Command Prompt & TPCOptimizer.

i don't know. just been using this new PC for 2 weeks.

i thought i'd find solution somewhere.

guess i'll call up ISP tech later today.

if your isp's dns server is crap just use another one.
