Trusted Domain Authentication issues

Intermittently we had servers that were unable to authenticate to the secondary domain - noobs
It seem that when the PDC2 was restarted the problem was fixed. I believe the servers switched to back to using PDC1 or another DC and were happy.

The trust was verified, etc but I think this was done on PDC1, started to annoy me... so had a look around.

On PDC1 there is a noobs.domainname secondary zone

On PDC2 Primary DNS is itself Secondary DNS being PDC1

On pdc2  was unable to resolve noobs.domainname
ping noobs.domainname
Ping request could not find host noobs.domainname

nltest /SC_Verify:noobs.domainname
Flags: 80Trusted DC NameTrusted DC Connection Status Status = 1311 0x51f ERROR_NO_LOGON_SERVERS
Trust Verification Status = 1311 0x51f
ERROR_NO_LOGON_SERVERS


[FIX] On Pdc2 Added a conditional forwarder for  noobs.domainname  to pdc1

nltest /SC_Verify:noobs.domainname
Flags: b0 HAS_IP  HAS_TIMESERV
Trusted DC Name \\ExternalPDC.noobs.domainname

Cleaning up old Windows Drive

Gettings trusted installer errors when trying to delete C:\windows folder
sooo

then..
takeown.exe /F D:\windows.old /R /A
icacls "D:\windows.old" /RESET /T /Q /C
rd "D:\Windows.old" /Q /S
or
for /f %i in ('dir /ad /b') do rd %i /s /q

Machine Password

Text file with list of servers - WindowsServers.txt

Grab the data

$CAITInfo = Get-Content .\CAITWindowsServers.txt | Foreach {get-adcomputer $_ -properties PasswordLastSet}

Filter and display

$CAITInfo | Sort-Object -descending PasswordLastSet | FT -property DNSHostname,PasswordLastSet

Grab Older than 30 days... which means either problem? or machine password not updating..

$CAITInfo | Sort-Object -descending PasswordLastSet|Where { $_.PasswordLastSet -lt (Get-Date).AddDays(-30)} |

FT -property DNSHostname,PasswordLastSet

To force a PC\server to reset machine password to AD (where not a DC)

nltest.exe /sc_change_pwd:lc.local

wonder if I can do that via powershell :)

ISA 2006 vs Cache Log vs liveupdate.liveupdatesymantec.com

So removing the ISA proxy @ work noticed while investigating who is still using the 'old' proxy.  Enable  reporting and the daily report for cache use always says "Information not available"

After thinking about  and then googling for the solution to this, didnt get any joy.

Logically it has to be what is set in the web proxy logging options. I remove a heap reduce the data in logs.
there is a options called 'cache information' , enabled that stuff now just need to wait till tomorrow to see if I have WIN.

reviewed the live log notice that' symatec live updates'   liveupdate.liveupdatesymantec.com are loggin as  cache information = 0x106

0x00000002 Request includes the IF-MODIFIED-SINCE header.
0x00000004 Request includes one of these headers: CACHE-CONTROL:NO-CACHE or PRAGMA:NO-CACHE.
0x00000100 Request includes the CACHE-CONTROL: MAX-AGE, or CACHE-CONTROL: MAX-STALE, or CACHE-CONTROL: MIN-FRESH header.

not so cool.

Think I need to force caching of this website. off to investigate
