It's not that uncommon unfortunately
As one of those affected, this happens a lot, our IT dept just warn us as if it is now routine. This particular outbreak was started last week according to our internal memo.
Every time the Govt loses data, we get more security imposed on us. In case we do the same. As a result we can't use any email account but our own and they all go through one IP for our PCT. As a result it gets worse each time.
MS are just shit at looking after their customers, given peoples lives are at risk you would think they would pull their finger out.
Personally I want the NHS to go from MS, third biggest employer, also third biggest customer to walk away????? We could pay any number of linux or apple makers to bring up a system to replace it, hell for the money we waste on MS we could write our own operating systems.
AC as I should be working.
