Jeste li naišli na pogrešku ' Kontroler domene Active Directory za domenu nije se mogao kontaktirati '? ^{(An Active Directory Domain Controller for the domain could not be contacted)}Većina korisnika iskusi ovaj problem dok žele dodati drugu Windows radnu stanicu^{(Windows Workstation)} na određenu domenu. Ovaj se problem u osnovi javlja kada želite dodati drugu Windows radnu stanicu u domenu. Ako analiziramo njegove uzroke, možemo zaključiti da postoje dva glavna razloga iza ove pogreške - pogrešna konfiguracija DNS-a i neispravan^(DNS) rad DNS -a. ^(DNS)Možemo li riješiti ovaj problem? Da, postoje načini za ispravljanje ove pogreške i dodavanje drugih Windows radnih stanica^{(Windows workstations)} u domenu.

Da biste dodali još jednu radnu stanicu sustava Windows^{(Windows Workstations)} , morate slijediti dolje navedene korake:

1. Desnom tipkom miša kliknite ovo računalo^{(Right-click on This PC)} i odaberite Svojstva^{( Properties)} da biste otvorili Svojstva sustava. ^{( System Properties. )}

2. Otvorit će se prozor sa svojstvima sustava. Kliknite ^(Click)Promjena postavki^{(Change Settings)} u desnom kutu ispod naziva računala, domene i postavki radne grupe^{( computer name, domain and workgroup settings)} .
