Windows 7 nonpaged pool Srv error 2017

I'm using a temp Windows 7 Server to share 2 lots of my shared files on-site while I waited for a new Dell Server to be delivered. So the problem I've been running into is that I use AD & a batch file to automatically map my users to this windows 7 box and their respective home folders & other folders, but my pc users are experiencing problems where they dont' get their drives mapped when they login - you have to either logoff and log back on or rerun the login batch file. I found this in the eventlog: Source: srv Event ID: 2017 Level: Error The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations. Someone suggested changing the following registry settings: Set the following registry key to ’1′: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache and set the following registry key to ’3′: HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size Followed by a restart of the server service.

Monitoring Pervasive PSQL with Nagios

Nagios 3.2.3 monitoring Pervasive PSQL running on Windows 2003 Server

To monitor Pervasive you have to monitor the following 3 executables:
The reason I monitor these executables instead of the service name is because the service name contains 2 brackets and Nagios refuse to monitor them.

Service names:
Pervasive PSQL Relational Engine - Pervasive.SQL(relational)
Pervasive PSQL Transactional Engine - Pervasive.SQL(transactional)


To monitor Pervasive you have to monitor the following 3 executables:

	Pervasive PSQL					NTDBSMGR.EXE
	Pervasive PSQL Relational Engine					w3sqlmgr.exe
	Pervasive PSQL Relational Engine Transactional					ntbtrv.exe

FREENAS 7.2 and FREENAS 8.0

After swearing continuously for 3 days I thought I'd share my experience about FreeNAS 7.2 and 8.0. Saying this·...I have to add that FreeNAS wasn't actually build to be a NAS connected to AD.


FREENAS 8.0


Negative points:

* Don't support AD on WIN 2008, don't give you access to the logs as it did in 7.2 (Diagnostics)
* Is an absolute mission to get AD setup and working (if you lucky)
* Is still hung-up about NETBIOS as in version 7.2
* Shutdown button on website
* Everything including SSH, AD is disabled and need to be explicitly enabled via "Services"
* Pity its build on FreeBSD
* CIFS & Windows Shares now 2 different things
* Website layout a bit confusing at first
* Total revamp from 7.2 to 8.0
* No upgrade option AT ALL from 7.2 to 8.0
* Do not use ZFS when connecting to AD

Positive points
* Nice website layout
* You can enable console messages under Settings
* Support VLAN's
* Support Windows Shares, UNIX, CIFS
* Access website without the :80 port indicator
* System - Reporting is nice

AD Debug Logs
Connect via SSH
Run /usr/local/bin/freenas-debug -a
cat /var/tmp/freenas-debug.txt


/usr/local/bin/freenas-debug ?


Logs folders
Console Logs  /var/log/messages/console.log
Machine related logs /var/log/messages


When SSH'ing into the box make sure you've ticked "root" user login under the SSH settings.
When SSH'ing use root and the "Website password" to login.


FreeNAS 8.0

FREENAS 7.2


Positive points
* Access to allot of the system logs from website (fantastic!)
* Much more usable & stable than 8.0


Negative Points
* Require reboot after most changes


After the setup:
* Make a note of the disk setup before you close the window!
* Add the disk  & DO NOT FORMAT
* Add a mount point
* Add a share
* Join AD
* Reboot
* Map the share on your AD, add folders, remove the second Everyone user from the share (The Everyone user that don't have any rights)
* Make sure the share is browsable
* Access the website ie http:10.0.0.99:80




AD Setup
When setting up AD you HAVE To do the following:
* Realize NetBIOS is very important to FreeNAS as this is what it use to connect to AD & network
* Enable the following 
*** EA
*** Dos Attributes
* Add the Server host name as a user on AD
* don't play around with the "net ad join" command as this will mess up AD completely

Remotely & Secretly auditing a PC (without user intervention)

Entering WMIC as domain administrator

1. From Start -- Run "runas /domain\user cmd"
2. You'll be shown a new command prompt window - now you are ready to use the WMIC   
3. "Windows Command Line Interface" 

Pulling installed software, name and versions from Remote PC's

1. To list software installed on a remote machine use the following syntax

wmic /node"PCNAME"  product get name, version, vendor >c:\somename.csv

Or you can pipe to .txt file for easier import into xls.

You will be shown the list of software installed on a PC & their versions: ie: and this will be piped to your c drive

Nagios - Monitoring Eventlogs on Windows Servers (My Comprehensive Guide)

Monitor DNS events on Windows Servers

• Copy eventlog_agent files to c:\
• Create folder on c:\ called "programme" 
• Create subfolder "eventlog_agent"
• Copy the eventlog_agent files (.exe, .bat, .reg) to c:\programme\eventlog_agent\
• Run eventlog_agent.exe (if doing it manually)

http://naplax.sourceforge.net/install_check_win_eventlog.txt

 Create /usr/local/nagios/etc/objects/eventlogs.cfg

• add "eventlogs.cfg" to nagios.cfg
• Add hosts to eventlogs.cfg

Contents - eventlogs.cfg

define service{

Errors

If eventlog.exe not running you'll get this error message

Current Status:	CRITICAL    (for 0d 0h 1m 57s)
Status Information:	An Error occured before state could be read: Connection refused at /usr/local/nagios/libexec/check_win_eventlog.pl line 145.

If errors continue - restart the .exe running on the host

To automate & install the .exe as a service

You will need 'instsrv.exe' and 'srvany.exe' from Microsoft Resource Kit.
Just copy those files together with 'eventlog_agent.exe', 'eventlog_agent.bat' and
'eventlog_agent.reg' into the folder 'c:\programme\eventlog_agent' and run the
batch file. If you want to use a different folder, then you will need to modify
the path in 'eventlog_agent.bat' and 'eventlog_agent.reg'
Autostart

You may put the exe into your Systems Autostart Folder. But this requires that there is
someone logged in.

Uninstall the eventlog_agent
If you used installation method a) or c), then can just delete the Files.
If you used installation method b), then you go into the installation directory
and call "eventlog_agent.bat stop" on the console.

The File Replication Service is having trouble enabling replication from BELL-AD-PRIMARY to SERVER1 for c:\windows\sysvol\domain using the DNS name Bell-AD-Primary.ambition24.com. FRS will keep retrying.
 Following are some of the reasons you would see this warning.

 [1] FRS can not correctly resolve the DNS name Bell-AD-Primary.ambition24.com from this computer.
 [2] FRS is not running on Bell-AD-Primary.ambition24.com.
 [3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers.

Troubleshooting:
* Check if SYSVOL is shared by using the "net share" command on all Servers?
* Is the FRS running on all Servers?
*  Run dcdiag and netdiag on both servers. to check

replication please run repadmin /showreps >rep.txt.

2.  Find IOS in flash memory (Tell router how to load by def flash)
3. IOS load and look for a valid configuration "startup config" stored in RAM or NVRAM
4. Once the IOS is loaded the POST information will be displayed
5. If no startup config is found in NVRAM the Router will go into "setup mode
