McAfee EPO 4.5 on Windows 2008 R2

Windows 2008R2 disabled the 8.3 naming conventions by default for performance reasons. McAfee's EPO product requires 8.3 naming, and will not install with it disabled. To enable it modify the registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

NtfsDisable8dot3NameCreation

Default value is 2, change it to 0 and reboot.

Converting static IP's to DHCP

Easiest way I've found to do this is to scan the subnet scope with nmap, and output the results to a text file. You can then put the text file into excel and use formula's to create a formated list. That list format can then be put into DHCP with reservations using a vbscript.

nmap is available at http://nmap.org/download.html

nmap -sP 192.168.1.0/24 > somefile.txt

Should give you a result like:

MAC Address: 00:14:38:D2:F5:3F (Hewlett Packard)
Nmap scan report for 192.168.1.1
Host is up (-0.12s latency).
MAC Address: 00:E0:81:56:AF:9E (Tyan Computer)
Nmap scan report for 192.168.1.2
Host is up (-0.12s latency).
MAC Address: 00:C0:02:A1:BC:5F (Sercomm)
Nmap scan report for 192.168.1.3
Host is up (-0.12s latency).
MAC Address: 00:26:55:14:31:47 (Hewlett Packard)
Nmap scan report for 192.168.1.4
Host is up (0.00046s latency).

Use excel to import and format the data so it shows as:

192.168.1.1,001438DCF53F
192.168.1.2,00E08156AF9E
192.168.1.3,00C002A1BC5F
192.168.1.4,002655143147

Save the file into a text document, named ListFile.txt.

You can then use the vbscript below to add the reservations to your DHCP server. The script must be run on a windows DHCP server.


Set fso = Wscript.CreateObject("Scripting.FileSystemObject")

Set shell = Wscript.CreateObject("Wscript.Shell")

Set ipList=fso.OpenTextFile("c:\ListFile.txt", 1, false)

Do While not ipList.AtEndOfStream
rLine=Trim(ipList.readLine)
MAC = Right(rLine, Len(rLine) - InStrRev(rLine, ","))
IP = Left(rLine, InStrRev(rLine, ",") - 1)
If not IP = "" or MAC = "" then
shell.run "netsh dhcp server scope xxx.xxx.xxx.yyy add reservedip " & IP & " " & MAC, 0, True

End If
Loop

You should of course double check any previous static IP documentation available, as nmap can easily miss devices configured to not respond.
