reduce number of Domain Controllers
Posted on 2009-07-13
I have a network I've inherited in a secondary school.
We have a fibre-optic backbone with gigbit switches linking together all the classrooms / buildings on site.
We have four Domain Controllers
1 x Exchange Server
1 x SQL Server
1 x Backup server
1 x NAS box
There are 1000 students, 70 teachers, 30 support staff.
400 client computers running XP Pro
We are on a support contract for the Windows Servers (as well as hardware warranty). Each Domain controller adds £750 to the support cost.
In 12 months time I plan to ditch the support contract altogether, but in the meantime I think I can reduce the DCs to two, thus simplifying things AND saving the school £1500 pa.
My question is this:
In what way might I need to improve the spec of the remaining DCs to cope with the demand?
Do I need to think about processor speed? RAM? Network connections?
The servers have two Xeon 3Ghz (single core processors); 2 Gb RAM; 1 x fibre and 1 x Gbit network connections
Services across the 4 DCs are:
Print Serving (40 printers)
User accounts (roaming profiles)
I don't have the budget for hardware replacement (new Servers) this year.
