Clock adjustment

One of our customers called me doubtfully: he was testing a custom SharePoint Designer workflow on their MOSS production server, and he would need some fire fighting: he set the server's time forward with 24 hours, then back. That was OK, but some things went wrong immediately: the main page gave "The Context has expired and can no logner be used." error message; the Content Query web parts returned with empty content; etc.

Althought the trouble was really serious (their full intranet was unabéle to work properly) the solution was quite simple: restart all SharePoint services, then run an iisreset. That's it, everything is working again.

Just a little "spillover": the current alerts were sent again for the users.
