Cannot open default admin shares on Windows 2008R2

CURRENT CONFIGURATION: Windows 2008 R2 SP1 (In workgroup), Windows 7

ISSUE: Cannot open default admin shares on Windows 2008R2 (C$, etc.) with account credentials in local Administrators group but the account is not Administrator. I could connect to non standard shares with the same credentials

C:\>net use \\MyServerName\c$ /user:MyServerName\MyAdminUser MyPassword

System error 5 has occurred.

Access is denied.

SOLUTION:

Please open regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Create new DWORD (32-bit) Value "LocalAccountTokenFilterPolicy"

Change in data 0 to 1

Please open Start –> Administrative Tools –> Server Manager –> Roles –> File Services –> Share and Storage Management

Right click on C$ –> Stop sharing

Open Command Promt as administrator

C:\>sc stop LanmanServer

C:\>sc start LanmanServer

Copy virtual machine on VmWare - network card issue

CURRENT CONFIGURATION: VMware ESXi 4, Ubuntu server 10.04

OBJECTIVE: Copy virtual machine on VMware

ISSUE: Network Card does not work after Linux virtual machine copy on VMware ESXi

All NIC are installed. Check command is

# lshw -C network

SOLUTION: 

to comment all lines in /etc/udev/rules.d/70-persistent-net.rules

# vi /etc/udev/rules.d/70-persistent-net.rules

Example:

# PCI device 0x8086:0x100f (e1000)
# SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:00:00:xx:01", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
# SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:xx:00:00:02", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

Please reboot the Ubuntu server on VMware ESXi.

For Ubuntu server clone (image) creation (moving preparation) use next command on master clone (Source server) before final poweroff (shutdown).

sed -i 's/SUBSYSTEM/#SUBSYSTEM/g' /etc/udev/rules.d/70-persistent-net.rules

upgrade to VMvare ESXi 4.1 Perl VIRuntime.pm issue

CURRENT CONFIGURATION: VMware ESXi 4.0

OBJECTIVE: upgrade to VMvare ESXi 4.1

ISSUE:

1. VMware vSphere Host Update Utility 4.0 can not update ESXi 4.0 to 4.1

2. Command(1) C:\Program Files\VMware\VMware vSphere CLI> vihostupdate.pl --server myESXserver_name_orIP -i -b k:\Downloads\VMWare\VMWare_ESXi\ESXi4.1\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA

returns next error message

Can't locate VMware/VIRuntime.pm in @INC (@INC contains: C:/My_different_perl_version_installation/Perl/site/lib C
:My_different_perl_version_installation/Perl/lib .) at C:\Program Files\VMware\VMware vSphere CLI\bin\vihostupdat
e.pl line 13.
BEGIN failed--compilation aborted at C:\Program Files\VMware\VMware vSphere CLI\
bin\vihostupdate.pl line 13.

 3. When you had renamed previously installed Perl Folder command(1) would return next window

4. When you added Perl with full patch to command(1) command(2) would return next error message:

Can't open perl script "vihostupdate.pl": No such file or directory

SOLUTION:

1. Download  and install VMware vSphere

2. If you have previously installed Perl please rename Perl installation directory temporary. Example: From  C:/My_different_perl_version_installation/ to C:/__My_different_perl_version_installation/

3. Add Perl with full patch to command(1). Would be command(2)  

C:\Program Files\VMware\VMware vSphere CLI> "c:\Program Files\VMware\VMware vSphere CLI\Perl\bin\perl.exe" vihostupdate.pl --server myESXserver_name_orIP -i -b k:\Downloads\VMWare\VMWare_ESXi\ESXi4.1\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA

4. Use full path for Perl and vihostupdate.pl. Would be command(3)

C:\Program Files\VMware\VMware vSphere CLI> "c:\Program Files\VMware\VMware vSphere CLI\Perl\bin\perl.exe" "c:\Program Files\VMware\VMware vSphere CLI\bin\vihostupdate.pl" --server myESXserver_name_orIP -i -b k:\Downloads\VMWare\VMWare_ESXi\ESXi4.1\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA

SOLUTION BOTTOM LINE:

If you have previously installed Perl please rename Perl installation directory temporary.

Use full path for Perl and vihostupdate.pl. Would be command

C:\Program Files\VMware\VMware vSphere CLI> "c:\Program Files\VMware\VMware vSphere CLI\Perl\bin\perl.exe" "c:\Program Files\VMware\VMware vSphere CLI\bin\vihostupdate.pl" --server myESXserver_name_orIP -i -b k:\Downloads\VMWare\VMWare_ESXi\ESXi4.1\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA

To VMware: Thanks for nice exercise.
