Submission Of Forms

Dear Sir,
I have IE 5.5, Windows 98 with 96 MB RAM. Whenever I try to submit a form,Sometime It goes well but most of the time the following massage appears, Page Expire or the following massage ? Check your DNS Settings?

So it is a very timeconsuming process to submit a form
Thanking you,
Manjit Singh
