 Troubleshooting Server unable to look up internal FDQN "result too large", unable to RDP to server, but can browse and read eventlogs

Quick answer: port exhaustion, kb out there to fix this stuff.

nslookup

 internalserver.internaldomain.local can't find internaldomain.local: unspecified error

1. clear dns servers

2. added dns servers in Core Data centre

3. tried different dns servers in nslookup

3a. tried local dns server

4. modified host file with internal.local to server

fail

Check firewall (disable)

netsh advfirewall set allprofiles state off

result:

ok

Check Group Policy

Gpupdate /force

result:

Updating Policy...User Policy update has completed successfully.Computer policy could not be updated successfully. The following errors were encountered:The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following: a) Name Resolution failure on the current domain controller. b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).

To diagnose the failure, review the event log or run GPRESULT /H GPReport.html from the command line to access information about Group Policy results.

check time

w32tm /query /peers

more nslookup

set debug

internaldomain.local

truncated answer

connect failed: result too large

check server's services

net stop dnscache

net start dnscache

net stop workstation

net start netlogon

Check Ports!

netstat -a -n

problem located - port exhaustion !!! 10000's of time_wait

there is a better rollup available(windows6.1-kb2775511-x64) but my server is not SP1. 

enjoy.

Change CD DVD drive letter RAGE - task sequence

echo select volume %%A >%temp%\movecdrom.txt

Build Import of DHCP Reservations - Powershell

Just followed ‘example 2’  - in the powershell command example  http://technet.microsoft.com/en-us/library/jj590686.aspx

Eg

Scopeid,IPAddress,Name,Clientid,Description

10.192.66.0,10.192.66.101,xx_L1_AP01,50-57-AC-9e-b1-26,SW - Gi1/0/47

10.192.66.1,10.192.66.102,xx_L1_AP02,d8-67-AC-95-5a-35,SW - Gi2/0/47

10.192.66.2,10.192.66.115,xx_L3_AP01,d4-8c-AC-04-72-e9,SW - Gi7/39

10.192.66.3,10.192.66.116,xx_L3_AP02,d4-8c-AC-2f-2b-ea,SW - Gi7/40

PS C:\> Import-Csv Path Reservations.csv | Add-DhcpServerv4Reservation -ComputerName koolkids.lc.local

pretty cool.

Powershell and DNS

Was trying to search for static address in a large subnet that I was working on.

start off with reading - http://gallery.technet.microsoft.com/scriptcenter/DNS-Server-PowerShell-afc2142b

retrieve the records with

$records = Get-DnsServerResourceRecord -ZoneName koolkids.internal -computer kcdc

tried

$records| ? recorddata -like "10.10.*"

got nothing returned... :(

then check the types:

$records | get-member

DistinguishedName         Property   string DistinguishedName {get;}

HostName                  Property   string HostName {get;}

PSComputerName            Property   string PSComputerName {get;}

RecordClass               Property   string RecordClass {get;}

RecordData                Property   CimInstance#Instance RecordData {get;set;}

RecordType                Property   string RecordType {get;}

Timestamp                 Property   CimInstance#DateTime Timestamp {get;}

TimeToLive                Property   CimInstance#DateTime TimeToLive {get;set;}

notice that is was CimInstance#Instance for the RecordData

can't remember how to convert it to string on the fly.

so my colleague suggested 

$records | out-gridview

then do the filtering from there, which work nice.

if after a few coffees I remember how to sort this out. I will update.

Stuck at "Please wait for the Group Policy client..." on Windows 2008 R2

My fellow workmate and myself were working on a two servers that were recently handed over to us.

These servers had multiple nics. Did the usual checked and also change the network provider order to have the "production" network first, because this it the way I roll.

We both joined the servers to the domain, rebooted and everything was fine, could logon etc.
my workmates server was  Stuck at "Please wait for the Group Policy client..."

So did the usual ; trying to view remote event logs, force a remote shutdown (which didn't work).
Decided that it was the fact that the bind order was stopping the logon from working
(Tried remote netsh, that didnt work remotely for some reason, most likely me)

Solutions to fix the problem to allow logon:
Add the blue cable
Add network cable to all NICs on the box (I dont have physical access to the box)
this should give IP address to all NICs


Disable NICs in BIOS
If you in the BIOS disable network card this might also be a option

Remote Connection and Disable the NIC(S) via netsh

1. download psexec from microsoft
2. connect to remote server psexec \\<servername> cmd.exe
3. perform a netsh interface ip show config or ipconfig /all
4. review the network setup, write down the names of the unused NICs or NICS with 169.254 addresses
5. go and disable the nics for example netsh interface set interface "Local Area Connection 3" DISABLED

make sure you don't disable the NIC you are working off! (of course)

Solution to fix the issue:
 change the network provider order to have the "production" network first,

Seven Segment Ardunio Gear Display

Was discussing that there is a upgrade for a stock part that would allow my bike to have a seven segment gear display for my motorcycle.

with leanings from - http://www.stanford.edu/~sanjayd/gear_indicator.pdf

once I know it works might paste it on gstwin.com
here is the code - let me know if I need to pastebin

// assume 7segment anode common
// might need pulldown resistors on the gear inputs 8-13
// might need  a filter,etc for the inputs
// would really like to use a 4 bit to 7 segment toget away from using 1,2,13 inputs
