How to ensure high availability solution for IIS hosted on Azure VM.
If site is hosted in IIS in azure vm, what if this vm goes down? Site will be inaccessible.
How can we make sure that site is redundant or highly available.
Load balancer / Traffic manager will distribute the traffic but not sure if VM hosting the IIS goes down.

Please correct my understanding also solution for this.. Thanks

Please bear with me, as this is going to be lengthy. The short of it is, I bought an SSL cert from GoDaddy for *.mydomain1.com. After installing it on IIS, I try to browse to the site on Chrome and get an SSL error NET::ERR_CERT_COMMON_NAME_INVALID. Looking at the Cert on Chrome, it says it's issued to *.anotherdomain.com. How is this even possible?

Here are screenshots of everything.

Note the two different SSL Certs in GoDaddy.

Hello we have a server with godaddy with Windows 2012 R2 and we configure the IIs 6 virtual smpt server  like:

In tab general (All unasigned)
In Access tab/Authentication anonymous
In access tab/Connection all except the list below and all is empty
In access tab/relay only the list below and the ”dedrelay.secureserver.net” and the IP of the server.
tab delivery/outbound connection just anonymous and checked TLS.
tab delivery/advanced we tested in FQDN the IP of the server above mentioned and also in a second test with the default full computer name. Then in both cases smart host we have “dedrelay.secureserver.net” and we have checked “Attempt direct delivery...”.

we have another server that is. it on godaddy and is Windows  2008 r2 we use an lms complex there and that email uses cdosys to send emails. We want to use or call in the server with Windows 2008 r2 the Windows 2012 r2 smpt. In other words we want to use the configuration above in smpt in the Windows 2012 r2 to use in the  Windows 2008 r2. How can we configure the Windows 2008 r2 smpt or anywhere to use the Windows 2012 r2 like the server to send emails?

Note: Both server are on different networks, in other words from two different companies, they don’t share anything in common.

We hope someone can help.

Thank you

Hi,

I am installing a IIS server, however I keep getting HTTP Error 500.0. Ive looked around the web and tried a few different things but nothing worked. Here are the steps I have tried so far:

Open IIS Manager.
In the navigation pane, click Application Pools.
In Application Pools, click SCEP.
In the Actions Pane, click Advanced Settings.
Under Process Model, click Load User Profile. Set toTrue.
Click OK to all open dialog boxes.
Restart IIS.

I also uninstalled and reinstalled the whole thing.

Any help would be greatly appreciated.

Hi folks, I'm looking for some best practices for a project that I'm working on.

Lets say we have webserver A and webserver B and both have an identical set of pages that represent a site. The two IIS servers are load balanced so incoming requests get sent to either one.

User hits the site and then does something that triggers a download or upload of a file that is temporarily stored on the IIS server in a work area for X duration. All of the IIS servers need to access the same "work area" because if the next request puts the user on webserver B, the data in the work area won't be present anymore.

Is the best way to address this situation to simply have a virtual folder that points to a common networked UNC on all the webservers so the data in that area will always be consistent?

It would seem to me that this would be the only way to accomplish this, but I'd love to hear if there was a better/slicker solution to this. Thanks!

Hi Experts

What is the Best Practice re IIS & RDS services?

We have 2 VMs on a HyperV: DC + RDS (both WIndows 2016)
Our CRM, ACT! from Sage,  is currently installed on the RDS but is only used internally.
We need to install a IIS / Web Server to give remote access to ACT! via the web

Can I use the RDS to install these additional components? My instinct is to build a new VM and install ACT! on that VM.

What says you?

Dear EE experts,

We would like to ask on how to resolve this technical issue that we're facing right now, we have SharePoint running, then just last week we changed IP, our whole company, system's IP were all changed to our new IP range, then our SharePoint site can't be access now...
If this problem is because of Database connection, because our SQL Server is located on the other server, its IP address has been changed too, if this is the case, how can we access the site of the localhost, as we even can't access the localhost site of SharePoint...

Kindly advise what went wrong and how to fix this problem...

Thank you and hope to hear soon...

We got a few of these email delivery failed messages today.     Our clients send out email messages thru our IIS 7.5 website.    We have SMTP running on the webserver.   This has been working great for a couple of years.    

One client today sent out a maybe 2 thousand email messages, higher then normal, all legitimate of course.        This was the FIRST time we saw these delivery failure.

And we always bcc an email address to ourselves such as Bill@[Company].com.  

Question:   Can we eliminate the delivery failure by raising our threshold of allows emails somewhere?    Do we do this at the "Reporting-MTA", which is our IIS box?    Or is this error coming from @[Company].com ?    GoDaddy hosts our email @[Company].com.


Reporting-MTA: dns;mail.[name of our website].com
Received-From-MTA: dns;[name of our IIS WEB server]
Arrival-Date: Thu, 5 Apr 2018 14:55:16 -0400

Has anyone made HTTP 2 HTTPS redirection work in IIS on Server 2016?

I have a simple published app in the /RDWEB folder that I'm publishing out to users.  I have the HTTP redirect working in that the users only need to type in the URL and it redirects to /rdweb, but I'd like anyone who enters HTTP to be redirected to the HTTPS site and I'm not having any luck.

I've used HTTP redirect and put in my https://url.com and that's not working (I even checked Only redirect requests to content in this directory, not subs).  No Joy.

I downloaded and installed the URL rewrite tool and made a rule to listen for http://myurl.com and redirect to https://myurl.com and still no joy.

I've read several web sites with various fixes, but none are working for me.  

Has anyone been successful in redirecting HTTP to HTTPS in Server 2016?

Thanks

Cliff

We have an web application server,  MS SQL Server  and a data storage server(separate physical machines)
Our applications are written in PHP and classical ASP. The PHP uses the CodeIgniter framework.
The applications have always worked well.
Using the command line, at the data server, login  as administrator, I can access the data, read, write etc.
But  the web applications can not  - neither PHP or ASP - access the data storage server.
We use Windows Server 2012. We are using MS SQL 2008.
I am sure it is a permissions problem, and after viewing the event log on the data storage server.
It appears to be so since I am receiving "Login Failure - SMB session authentication failure" messages .
I am not sure of how set up permissions on the data storage server so the web applications can use it. I mean, I don't want to enter each person etc.
I am not finding much info on this problem.
Can someone guide me in what I need to check etc. to resolve this problem.
This is really urgent, any help appreciated.

I've implemented a redirect to a new domain on a legacy BlogEngine install (running on ASP.NET).

The redirect itself works fine. You'll see I'm effectively removing the 'post' folder from the destination url etc.

Issue is that this is returning a HTTP Status of 200. I need to return a 301 for best SEO. I'd thought specifying redirectType of Permanent would have handled that. Any ideas?

<rewrite>
      <rules>
        <rule name="redirect" enabled="true">
          <match url="^post/(.*)" />
            <conditions>
              <add input="{HTTP_HOST}" negate="true" pattern="^www.OldDomain.com/sharepoint/post/$" />
            </conditions>
          <action type="Redirect" url="https://NewDomain.com/{R:1}" appendQueryString="true" redirectType="Permanent" />
        </rule>
		<rule name="redirectFolder" enabled="true">
          <match url="(.*)" />
            <conditions>
			  <add input="{HTTP_HOST}" negate="true" pattern="^www.OldDomain.com/sharepoint/$" />
            </conditions>
          <action type="Redirect" url="https://NewDomain.com/{R:1}" appendQueryString="true" redirectType="Permanent" />

Hello,

I am looking at a Windows 2012 IIS server and I see a certificate WMSvc-myiisserver that has an expiration date of 1/20/2015 and it is using SHA1.

I do not recall I ever deploy that certificate on the server.

Would someone advise if that cert is always there by default?  Where do I go to see the vendor of that certificate?

Please see the attached.  

Thanks.

I cannot figure out why my PHP installation is requesting a physical path without an extension.

Requested URL http://localhost:80/index
Physical Path C:\inetpub\wwwroot\index



PHP is working fine with phpinfo.

I have tried Googling and to my surprise no results related to a physical path showing no extension. I'm sure I'm missing something silly in the php.ini or something. Any help is extremely appreciated!

Hello,

Our team is being told to investigate whether our Windows infrastructure contains misconfig encryption.  

I sample a few WIN2012 web servers, open up the registry and look at the secured channel settings.  I see TLS 1.1 client and TLS 1.1 server are enabled.  Some servers have SSL 2.0 client presents but not enabled.  No SSL 3 or TLS present.

Would somone educate me how the secured channel protocols being added into the registry?  

I understand that SSL 2 and 3 are old and they should be disabled.  What is the best way to ensure the disable process will not affect our current applications?

I usually deal with adding secured certificates to the web servers but do not pay attention of what schannel protcol is used.  

Thank you very much.

Hello,

I currently have a VPS with RDP at my provider CWH, but my domains are with GoDaddy with A-Records pointing to CWH; and Emails with Microsoft Exchange.  Whenever I need to create a subdomain, I first log into GoDaddy create a new A-Record, then log into Plesk at CWH and create my sub domain there.  

As I’m releasing anew service, I’m hoping to automate this, so I had the following questions.

1.      Can I host my own DNS on my VPS? I

a)      If yes, could I use an API or SDK to create and delete A-Records?

b)      If no, do you know if GoDaddy or another provider has such interface?

2.      Within Plesk, or IIS directly, how can I Create/Suspend/Delete subdomains… again by code? Plesk is PHP-based, so there must be a way.

Obvoiusly my VPS is IIS, but can get Linux.

Any advice would be appreciated.
