SharePoint disable loopback check | Specify Host Names

A number of errors related to authentication failure are reported with SharePoint 20xx

You can try disable loopback check  or Specify host names based on how much you can compromise on security front.

Method 1: Specify host names (Preferred method if NTLM authentication is desired)

To specify the host names that are mapped to the loopback address and can connect to Web sites on your computer, follow these steps:

1. Set the

DisableStrictNameChecking
registry entry to 1.

2. Click Start, click Run, type regedit, and then click OK.

3. In Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
4. Right-click MSV1_0, point to New, and then click Multi-String Value.
5. Type BackConnectionHostNames, and then press ENTER.
6. Right-click BackConnectionHostNames, and then click Modify.
7. In the Value data box, type the host name or the host names for the sites that are on the local computer, and then click OK.
8. Quit Registry Editor, and then restart the IISAdmin service.

 
Method 2: Disable the loopback check (less-recommended method)

The second method is to disable the loopback check by setting the DisableLoopbackCheck registry key.

To set the DisableLoopbackCheck registry key, follow these steps:
1. Set the
DisableStrictNameChecking
registry entry to 1.
2. Click Start, click Run, type regedit, and then click OK.
3. In Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
4. Right-click Lsa, point to New, and then click DWORD Value.
5. Type DisableLoopbackCheck, and then press ENTER.
6. Right-click DisableLoopbackCheck, and then click Modify.
7. In the Value data box, type 1, and then click OK.
8. Quit Registry Editor, and then restart your computer.

                                                 or
$regKeyPath = "HKLM:\System\CurrentControlSet\Control\Lsa"
$key = "DisableLoopbackCheck"
New-ItemProperty -Path $regKeyPath -Name $key -Value "1" -PropertyType dword

refer unsigned assembly in SharePoint 2010 Project ( Visual Studio 2010)

I have around 50 3rd party dll's which I need to refer in my SharePoint project.
But since my project dll is strong named we were unable to refer unsigned dll's in it.
I tried below mentioned things:
1. removed signing of my dll from project properties. Project is build But in this case xml template of the package fails .The error I get while package creation is :
Value cannot be null. Parameter name: PublicKey
2. I tried below mentioned commands to strong name all the 3rd party dlls :
ildasm myDLL.dll /out:myDLL.il
This generates myDLL.il and myDLL.res
ilasm myDLL.il /key:Key.snk /res:myDLL.res /dll /out:myDLL.dll
This generates back strong named DLL.
But after this few of the namespaces get missing in the final DLL !!!!! well to my surprise .
3. I created a blank class library project . Given predefined structure to deploy 3rd party dll ( 80\bin) , with user controls inside proper structure as per wspbuilder guidelines. given the output path of my project dll as (80\bin).
Now I have a wsp ready and working being deployed . But neither my project dll is strong named nor the third party DLLs. dlls are deployed in web application bin and user controls inside proper control template folders . They work fine . but …
Now I come to my query:
I need to strong name my project dll still use 3rd party unsigned dll's inside my SharePoint project very similar to point 2 above.
Kindly suggest something.

Ask the 3rd party to provide properly signed assemblies?

Might be a good option to wrap your business logic up that uses the DLLs in a WCF service and run it outside SharePoint, then you can call these methods safely from inside SharePoint (are you writing web parts?).

1. Use IlDasm to disassemble the DLL to an .il File

2.  Then use IlAsm to reassemble it passing in a new key generated with the sn command line utility to generate strong names.

Make sure you use the .Net 3.5 versions of ILDasm and ILAsm or it will reassermble the Dll for the wrong framework, sharepoint  2010 stuff is .Net 3.5

The downside is you'll have to do that everytime a new version comes around.

This is how I got the .Net 3.5 version of the AJAX Control Toolkit to work in sharepoint 2010.

 

Heres a pretty in depth article that even covers signing DLL's that reference each other.

Analyse event logs for Service Control Manager activities from windowsservices

Sometime you might want to start and stop kind of activities out of event logs for windows services . here is powershell script for this
$eventL = Get-EventLog -LogName "System" -Source "Service Control Manager" ;
Get-Service | ForEach-Object {
$st1 = "";
$st2 = "";
$st3 = "";
$st1 = $_.Status;
$st2 = $_.DisplayName;
$st3 = $_.Name;

#Write-Host $st1 $st2 $st3 -foregroundcolor cyan;

$eventL | where { $_.Message.Contains($st2) -eq "true" } | Select-Object -First 1 | ForEach-Object {

Write-Host $st1 $st2 $st3 -foregroundcolor cyan;
$st4 = "";
$st5 = "";
$st4 = $_.Message;
$st5 = $_.TimeGenerated;
Write-Host $st4 $st5;

}

}
$eventL = $null;

Now that you have decided the culprit windows service, use this script to get whole available history:

$eventL = Get-EventLog -LogName "System" -Source "Service Control Manager" ;

Get-Service | ForEach-Object {

if($_.Name -eq "AAAAAAAAAAAA"){

$st1 = "";
$st2 = "";
$st3 = "";
$st1 = $_.Status;
$st2 = $_.DisplayName;
$st3 = $_.Name;

#Write-Host $st1 $st2 $st3 -foregroundcolor cyan;

$eventL | where { $_.Message.Contains($st2) -eq "true" } | ForEach-Object {

#Write-Host $st1 $st2 $st3 -foregroundcolor cyan;
$st4 = "";
$st5 = "";
$st4 = $_.Message;
$st5 = $_.TimeGenerated;
Write-Host $st4 $st5;

}

}

}
$eventL = $null;

Might be the case , you only want to list down which service is stopped and which one is active :

Get-Service | ForEach-Object {

$st1 = "";
$st2 = "";
$st3 = "";
$st1 = $_.Status;
$st2 = $_.DisplayName;
$st3 = $_.Name;

Write-Host $st1 "," $st2 "," $st3 -foregroundcolor cyan;

}

Multiple TargetPath under EcmDocumentRouterRule | EcmDocumentRouter , Content Organizer Rules , SharePoint 2010

In SharePoint 2010 with Content organizer  Feature, we can route a document to the target based on predefined rules.

If multiple rules condition satisfy for current document being put in drop off library, priority of rule decides which rule will run.

 

My requirement is :

Either

1. Run multiple rules for single document so that same document may be routed to multiple targets.

Or

2. Under single rule define multiple targetpath so that single document may be routed to multiple locations base don predefined rules.

Hi,

If you want to implement the requirement you mentioned, it is not necessary to use the Content Organizer feature.

You can create an 'ItemAdded' event receiver for all the document libraries. After you uploaded document to library, you can call the method 'SPListItem.CopyTo()' to copy current document to destination.

For this topic you can see the following document.

Chen,

What if I want to avoid customization using Object Model. Can the content organizer then help in this. I have a similar requirement to this. I have location property which is multi value field. Based on the selections need to route the document to the appropriate folders. Can you please highlight how this can be achieved?

Thanks,

Mayur

In your case it is achivable out of box.

 

Define as much rules as much you have targets.

 

In the condition of each rule you can define, based on meta data field( which is your location ) route the document to desired target.

Hemant,

Wish that was the case, i cant set as much rules because numerous permutation and combination that can happen with the countries (its a multi choice field).

I have raised another thread located here explaining the entire scenario. Any help will be highly appreciated.

Thanks,

Two exactly same strings fail while comparison in c# .Net

I had an input field which had a space , some browsers were giving different hex for space in these input fields.

Finally I found , a space may not be a space there are as much as 25 different representations for space in Hex.

.Replace((char)0xA0, ' ') worked but better way is using .Normalize(System.Text.NormalizationForm.FormKC)

"Central Administration>General Application Settings>External Service Connections >Configure Send To Connections" code for this

This is the way we define a connection to a site where we would like to drop our documents.

 

Now in my case there could be hundreds of target sites created by code as and when required.

For each site created I want to write few lines of code which will do exactly what /_admin/OfficialFileAdmin.aspx  page does.

 

 

So i want code for what /_admin/OfficialFileAdmin.aspx ( Central Administration>General Application Settings>External Service Connections >Configure Send To Connections) does.

 

 

just try out like:
SPWebApplication app = SPWebApplication.Lookup(new Uri("http://hemant1236"));
SPOfficialFileHost host = new SPOfficialFileHost(true);
host.OfficialFileUrl = new Uri("http://hemant1236/testsite1/_vti_bin/officialfile.asmx");
host.OfficialFileName = "hemant1236Test1saurabh";
host.ShowOnSendToMenu = true;
host.Action = SPOfficialFileAction.Move;

host.Explanation = "created at Time" + DateTime.Now.ToString() + " by custom utility.";

app.OfficialFileHosts.Add(host);

app.Update();

In the app keys for main web application which is being extended; there was a key which referred a shared location like : "\\hemant1236\dropOff". The characters \\ in this app keys were the culprit. When I commented out this key , the web application was able to extend successfully.
