Installing .NET Framework 3.5 on Windows Server 2012 and Windows Server 2012 R2

There might be requirements of installing .Net Framework 3.5 in Windows Server 2012 and Windows Server 2012 R2, and you will most likely run into problems while installing it.

If you are trying to install .NET Framework 3.5 from the Server Manager GUI, you will see this when installing the feature:

“Do you want to specify an alternate source path? One or more installation selections are missing source files…”

Confirm

 

 

To solve this, you can either:

1. Go to a command prompt and enter this:

dism /online /enable-feature /featurename:NetFX3 /all /Source:d:sourcessxs /LimitAccess

Note: Source should be the Windows installation disc. In my case, this was located on D:

command

2. Go down to “Specify an alternate source path” and enter “d:sourcessxs” as the path.

Now you can proceed with installation.

How to Set MaxPageSize in Active Directory

Certain LDAP clients can only receive the first 1,000 results when they make an LDAP query to Active Directory, when more results exist that satisfy the query scope.  If there are 1,200 results to be returned, the client will receive the “Size Limit Exceeded” error when the paging control is not used.

Microsoft lists MaxPageSize as:

MaxPageSize – This value controls the maximum number of objects that are returned in a single search result, independent of how large each returned object is. To perform a search where the result might exceed this number of objects, the client must specify the paged search control. This is to group the returned results in groups that are no larger than the MaxPageSizevalue. To summarize, MaxPageSize controls the number of objects that are returned in a single search result.

Default value: 1,000

Here are the steps for showing and changing the default MaxPageSize in AD.

Microsoft releases emergency update to patch Internet Explorer bug

Microsoft has released an emergency update to patch a security vulnerability in Internet Explorer that is being exploited in attacks aimed at government contractors and other targeted organizations.

The patch fixes a “use after free” bug in versions 6, 7, and 8 of the Microsoft browser and will be automatically installed on affected machines that have automatic updating enabled,The unscheduled release comes just six days after Microsoft’s most recent monthly Patch Tuesday batch of security updates, but it was pushed out to counter an experienced gang of hackers who have infected websites frequented by government contractors to exploit the vulnerability.

Monday’s update came hours after Oracle released an unscheduled patch to fix a critical vulnerability in its Java software framework. As reported last week, the zero-day Java exploits were added to a variety of exploit kits that criminals use to turn compromised websites into platforms for silently installing keyloggers and other malware on the machines of unsuspecting visitors.

The attacks exploiting the IE vulnerability, by contrast, targeted a much narrower set of people, researchers said. Such campaigns have come to be dubbed “watering hole” attacks, because they’re akin to hunters who hide out at ponds or other sources of water and wait for their prey as they quench their thirst.

Versions 9 and 10 of IE are more resistant to security attacks that aren’t vulnerable to the exploit. If possible, readers should install one of those versions.

Microsoft previously issued a “Fixit” tool to mitigate the effects of an attack. People who have applied the temporary fix do not need to uninstall it before installing the permanent patch. Still, Microsoft suggests users uninstall the FIxit once the patch is in place. The patch is not a cumulative batch of previous IE fixes, so users still must apply MS01-077 to be protected against vulnerabilities Microsoft patched last week. The company’s advisory is here.
