a fair bit across varied areas.Haven't played with Windows Servers myself since the 03 version.
Lots of level 1 work on fixing desktops and printers
Can strip an rebuild laptops.
Old work had me build one of there Linux servers. After them having it 18 months and never getting it into production I had it up and running and through testing within 6 months (very strict testing they wanted especially after their f**kups). I actually hear that the system ran for 5.5 years without a single fault, they just replaced it as a preventative measure.
I used to be able to hack code together in java, specifically for HMI displays that talked to PLCs to run part of a steel works.
I use to be able to code well in C, haven't touched it in 5 years though, can read it, but don't know it fluently any more.
And I do a bit of hacking together with PHP and mySQL as a past time.
Have my own ML350 server at home, doing a fresh load on it at the moment as my acquisition centre, and file server.
As for work, I just talk it up... I'm a consultant, primarily dealing in SMB. Haven't actually touched the tools professionally for about 3.5 years. Have done plenty for myself and others but not as a job.
