IP Addressing:

IP Addressing:

There are two versions of IPs

1. IP version 4: offers IPs up to 4.2 billion (32 bit size)

2. IP version 6: 128 bit size.

IP address is used for identifying the system and provides communication.

IP address is of 32 bits divided in four octets.

Each Octet is of 8 bits, separated by a (.) dot.

IP is a combination of Network ID & Host ID.

Uses subnet mask to differentiate Network ID with Host ID.

Subnet mask acts like a mask between Network ID & the Host ID.

Numbers range between 0-255.

Organizations responsible for assigning IPs to clients.

IANA: Internet Assign Naming Authority.

ICANN: Internet Corporation assigning for name Numbers.

IANA has classified IP addressing into classes.

Class A:        1-126(used in LAN/WAN)

Class B:        128 – 191(used in LAN/WAN)

Class C:        192 – 223(used in LAN/WAN)

Class D:        224 – 239 (used for multi casting)

Class E:         240 – 254 (used for experimentation & research)

Class	Format	No of N/Ws	No of Hosts	Subnet mask	Range
A	N.H.H.H	28-1   126	224 – 2 16.777.214	255.0.0.0	1 – 126
B	N.N.H.H	216-2  16.384	216 – 2 65.534	255.255.0.0	128 - 191
C	N.N.N.H	224-3  2.097.152	28 – 2   254	255.255.255.0	192 – 223
D	MULTICAST	N/A	N/A	N/A	224 – 239
E	RESEARCH	N/A	N/A	N/A	240 - 254

Class A:The first octet is reserved for network ID.

The first bit of first octet is always (0).

Class B: The first two octets are reserved for Network IDs.

The first two bits of first octet are reserved as (10)

Class C: The first three octets are reserved as network portions.

The first three bits of first octet are reserved as (110)

Class D: Used for Multicasting.

The first four bits of first octet are reserved as (1110)

Class D: Used for Experimentation.

The first four bits of first octet are reserved as (1111)

The first bit of first octet is called as priority bit which determines the class of N/W

0.0.0.0. Are reserved as N/W ID.

255.255.255.255 is reserved as broadcast ID.

127.0.0.1 Is reserved as loop back ID

On Desktop

Right click on my network places-properties

Double click local area network-Select properties

Click-Use the following ip address

Specify the address in the box

DNS also same as IP address.

Verifying:

Go to command prompt

Type” ping IP address”. (PING: Packet Internet Groper)

SCCM: How to Exclude Files From Software Inventory

How to Exclude Files From Software Inventory

You can create a hidden file named Skpswi.dat and place it in the root of a client hard drive to exclude it from software inventory. You can also place this file in the root of any folder structure you want to exclude from software inventory. This procedure can be used to disable software inventory on a single workstation or server client, such as a large file server.

The Skpswi.dat file only prevents software inventory for computer clients and does not affect mobile device client inventory.

Software inventory will not inventory the client drive again unless this file is deleted from the drive on the client computer.

To exclude files from software inventory

1. Using Notepad.exe, create an empty file named SkpSwi.dat.
2. Right click the SkpSwi.dat file and click properties. In the file properties for the SkpSwi.dat file, select the Hidden attribute.
3. Place the SkpSwi.dat file at the root of each client hard drive that you do not want to collect software inventory from.

Tip: how can I target applications to specific hardware (just a tip ignore if you know this pls)

http://www.windows-noob.com/forums/index.php?/topic/563-how-can-i-target-applications-to-specific-hardware/

also you can use below query if you want to create a collection based on hardware:

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceID = SMS_R_System.ResourceId where SMS_G_System_COMPUTER_SYSTEM.Model in ("Latitude D420","Latitude D630","Latitude D430","Latitude D620")

Note: you can change hardware models based on your requirement in the query.

To increase log file size on SMS/SCCM client: ConfigMgr : Verbose and Debug Logging

To increase log file size:  ConfigMgr : Verbose and Debug Logging

64 Bit machine:

============

1.       In registry, go to HKLM > Software > WOW6432Node > Microsoft > CCM > Logging > @Global

2.       Right click on @Global and click on Permissions. Grant Administrators group with Full control.

3.       Modify the key: “LogLevel” and set the value from 1 to 0 –{This enables Verbose logging}

4.       Now, right click on Logging and create a new key and name it: DebugLogging

5.       Under DebugLogging, create a new string named: "Enabled" ->{Without Quotes}, and set the value to "True" ->{Without Quotes}. –{This enables Debug Logging}

32 Bit machine:

===========

1.       In registry, go to HKLM > Software > Microsoft > CCM > Logging > @Global

2.       Right click on @Global and click on Permissions. Grant Administrators group with Full control.

3.       Modify the key: “LogLevel” and set the value from 1 to 0 –{This enables Verbose logging}

4.       Now, right click on Logging and create a new key and name it: DebugLogging

5.       Under DebugLogging, create a new string named: "Enabled" ->{Without Quotes}, and set the value to "True" ->{Without Quotes}. –{This enables Debug Logging}

Once done restart the SMS AGENT host Service and wait for 10
