I am experiencing problems with a packard bell P3-500 machine with 128 meg ram and a standard dial up modem/connection. It is connecting to the internet perfectly and connection speed is fine. Finds home page without any problems but then when attempt to access Hotmail (and certain other) sites - web site is found but progress bar gradually edges along but site never appears. Pinged site (through dos prompt) and request timed out. However tried a number of other (.net, .com, and .co.uk) sites and and they worked fine. Tried same computer with a different dial up connection (UK2 ISP) but still would not access hotmail. Tried to access hotmail from my laptop (UK2 ISP - IR modem) - and it got through fine. Also all other computers on the site which use the same dial up connection and modem as the problematic computer were able to access all sites without any difficulty.
As it is independent of both the dial up connection and the web-sites themselves it would appear to be a local problem with the computer, but I know of nothing that can manifest itself as a selective inability to access certain websites. The computer has recently had zone alarm and norton installed, but i disabled these and the problem sites were still inaccessible - also all working computer have the two packages installed without any trouble. Also I checked the internet security settings - and there was nothing abnormal here.
I would be grateful for some feedback.
