XP Pro SP3, Server Service disabled, no file sharing. I noticed recently this 'PerfNet' red cross in Applications, event Viewer, which I am not sure when it started,but I am positively sure I didnt have in the past in spite of always running XP with Server service disabled. A search for a possible solution brought to downloading Windows XP Service Pack 2 Support Tools running "exctrlst" and unflagging Performance Count Enabled in PerfNet. I think it might work, in spite of my OS not being in English, but I am hesitating on account of the fact my XP is SP3, whereas the solution needs an SP2 tool. Can this 'tool downgrade' be done with satisfactorily results? Given the fact this error-warning came about at a certain point in the OS life-which was always deprived of those useless Services as advised by Black Viper more or less- I surmise that it all comes down to a certain program not behaving well at start,rather than a lack of the Server function. Consequently,can anyone who experienced the same error please point me to a lighter solution which does not need the download of any Reskit or assorted Tool from MS? (if there's one). karad XP Pro SP3,Avira,PrevX,ComodoD+,Returnil,KeyScrambler.
