Restarting server never comes back

Situation: The client has a server running Windows 2008 R2 server. Whenever they restart the server, it shutdown but never comes back. They need to turn it off manually and then turn it on. In other words, warm reboot doesn’t. It works only cool reboot.

Troubleshooting: We find there is a dead USB drive connecting to the server. Removing it from the server fixes the problem.

Solution: Increase the shadow copy storage area for the volume listed in the error event, or set the maximum size to “No limit” by following these steps:

  1. Right click any volume and choose Configure Shadow Copies.
  2. With the Shadow Copies utility open, select the volume with insufficient space;
  3. Click Settings…
  4. In the “Maximum size” box, either increase the limit, or choose “No limit”.

 

 

How to export/import domain account information

  1. Export from DomainA:

csvde -f C:\Rename\export_AD.csv -m -n -o “primaryGroupID,lockoutTime” -j C:\Rename\Logs

Where:

-f filename to export to

-m do not export SAM values, e.g. objectSID

-n do not export binary values

-o exclude named columns

-j folder to log to (produces csv.log, plus csv.err if any errors occured)

2. Edit the export_AD.csv file as follows:

Delete the lines beginning:

o   “CN=Builtin …       (1 expected)

o   “CN=Infrastructure… (1 expected)

Delete all lines containing:

o   ,samServer,     (1 expected)

o   ,rIDSet,           (1 expected)

o   ,secret,           (4 expected)

o   ,rIDManager,       (1 expected)

Remove any ‘box’ (ASCII 13) characters in the text:

o   Unfortunately these cannot be searched for in Notepad

o   There may be one in the commas at the end of each of the last 50 lines in the file

Replace all instances of ‘PCOld’ with ‘PCNew’

o   Where PCOld is part of the machine name and domainname

3. Import into DomainB:

csvde -i -f C:\Rename\export_AD.csv -k -j C:\Rename\Logs

o   -i import

o   -f filename to export to

o   -k ignore non-serious errors (e.g. object, attribute or value already exists)

o   -j folder to log to (produces csv.log, plus csv.err if any errors occured)

How to Configure IPSec VPN on Paloalto Firewall

  1. With Palo open, go to Network >Interface > Tunnel,  click Add to create a new tunnel interface and enter the following info:
    Name: tunnel.1

Comment: Chicagotech VPN or any comment.
Virtual router: Default or any existing virtual router you have.
Security Zone: DMZ (It must be the layer 3 internal zone from which the traffic will originate)2. Go to Network > Network Profiles > IKE Crypto , click Add and enter the IKE Crypto profile (IKEv1 Phase-1) parameters. These parameters should match on the other site firewall for the IKE Phase-1 negotiation to be successful.

3. Go to Network > Network Profiles > IKE Gateway to configure the IKE Phase-1 Gateway. There are 3 options for the Version where you can select IKEv1 only mode, IKEv2 only mode or IKEv2 preferred mode. Two sites must use the same mode, for example IKEv2 preferred mode. Enter al other info.

4. Under Network > Network Profiles > IPSec Crypto , click Add to create a new Profile, define the IPSec Crypto profile to specify protocols and algorithms for identification, authentication, and encryption in VPN tunnels based on IPSec SA negotiation (IKEv1 Phase-2). These parameters should match on the remote firewall for the IKE Phase-2 negotiation to be successful.

5. Under Network > IPSec Tunnels, click Add to create a new IPSec Tunnel. In the General window use the Tunnel Interface, the IKE Gateway and IPSec Crypto Profile from above to set up the parameters to establish IPSec VPN tunnels between firewalls.

6. When configuring an IPSec Tunnel Proxy-ID configuration to identify local and remote IP networks for traffic that is NATed, the Proxy-ID configuration for the IPSec Tunnel must be configured with the Post-NAT IP network information, because the Proxy-ID information defines the networks that will be allowed through the tunnel on both sides for the IPSec configuration.

7. Under Network > Virtual Routers, click on your Virtual router profile, then click Static Routes, add a new route for the network that is behind the other VPN endpoint. Be sure to use the proper Tunnel Interface. Click OK when done.

8. Save all settings.
