Our office network is split into 2 internet service providers so that we have failsafe connections to the internet. These 2 gateways occasionally go down on certain computers, and this causes those users to no longer access certain websites (eg our corporate website which is served overseas).
Interestingly this issue can be resolved for each individual user by typeing in the following command in XP Command prompt:
The tracert then returns a timesout when it nears the corperate website, but seems to then work when the user browses to the site in any browser again.
How can I avoid having to get users to perform this task? Why is performing a tracert fixing the problem?
