Show available wireless networks using netsh (Provides more info than GUI):
netsh wlan show networks mode=bssid
Powershell command to replace a line of text in files recursively, in this example we disable bitmap cache in all Default.rdp files
gci "C:\Documents and Settings" -recurse -force -filter default.rdp | % { Set-Content $_.FullName ((gc $_.fullname) -replace "bitmapcache.*","bitmapcachepersistenable:i:0" )}
Use the following command to list MS DNS Server cache entries:
dnscmd DNS_Server_IP /enumrecords /cache domainname
Use /detail for additional info

Example of createing a counter eventlog from commandline using logman
md d:\Perflogs
cacls d:\perflogs /e /g "NT AUTHORITY\NETWORK SERVICE":C
logman create counter PerfLog2010 -o D:\Perflogs\ -rf 168:0:0 -si 0:0:15 -f bin -max 512 -v mmddhhmm
