HTTP Error 500.19 - Internal Server Error

[Anon Anon]

Good day,

I have installed RA9.0.161 on Win2008 R2 64bit as a staging upgrade phase for a client we need to upgrade, now trying to login through web interface after completing the install, I get HTTP Error 500.19 - Internal Server Error. I then followed the tip about assigning tthe recommended permissions to the IUSR local account and rest IIS, I still get the 500 Internal Server error. Not sure what I am missing yet. I have not installed NPC as yet, need to get through this first before I can do NPC installation.

 

Please advice.

HTTP Error 500.19 Internal Server Error

 

Document ID:  TEC590944

Description:

You may also see this error message displayed in the views on a page (the page itself loads ok):

 

Error: Unable to validate data source credentials. Please make sure to provide the right credentials for your data source. This second error is because the views in NV are trying to connect to the pollers web service, and are failing due to the same permission issue that causes the error 500.19 issue on the master.

Solution:

This is caused by incorrect version of .NET and can be resolved by:

1. Check if .NET 4.0 has been installed and IIS 7.0

 

1. If .NET 4.0 is installed you must uninstall .NET 4.0 . You can uninstall this from "Control Panel->Uninstall Programs".

 

1. Recycle IIS after this is done and verify .NET 3.5 SP1 is still installed.

 

1. Verify access to the Web Console

Thanks Mustafa for your response,

 

I have .NET3.5.1 installed and IIS 6.0. Should I uninstall IIS 6.0 and install 7.0?

Morongwa, did you ever resolve this problem?

If you are using IIS 6.0, it sounds like you are on Windows 2003 so you may have a slightly different problem here.

 

Also .NET 4.x will show up only in Control Panel->Add/Remove Programs, so you may want to check there as well.

Hi Chris,

 

I am on Win2008. For some reason, I had IIS 6.0 and 7.5, but I uninstalled 6.0 and reset IIS. Now the error is pointing to credentials on the DB and the console.

 

I have checked the netqos services, the log on credetials are using  local system account, seeing that when you create a user on Win2008, you cannot use defauslt password used by RA because of password policy requrements, will it have an impact if system local netqos and nqadmin accounts are using different passwords from the normal default netqos and nqadmin accounts?

 

If it does, where do I change the passwords for DB and application to match the system local accounts?

What is the exact error you are seeing now, can you share a screenshot?

 

The windows system accounts do not have anything to do with the RA/NFA Web login.

So it doesn't matter if the nqadmin exists as a windows system account, nor does it matter what the password is.

 

Usually if IIS is complaining about a user account, its going to be the Windows IUSR account.  You should make sure that account is a member of the local Administrators group.

[Anon Anon]

Hi Chris,

 

IUSR is part of Administrators group, I made sure I added it. When I access the web interface I get directed to a list of the attached links(login error1) as the first error

The first link on the attachment redirect me to the RA portal page that shows Access Denied, and it seems as if it logs in as "administrator" account without prompting me to login, see login error2 attached,

 

Not sure what could be changed to make this right as I have went through the install tips on community plus installation guide.

 

Thanks

Morongwa, for the problem where you see the directory listing, follow the doc below:

 

http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec595777.aspx?intcmp=searchresultclick&resultnum=1

 

You should also be able to use http://localhost/ra/default.aspx

[Anon Anon]

Morning Chris,

 

I have followed the knowledgebase article and found that the default.aspx exist already, also moved it up the list to improve performance. I now get the below  error when I use http://localhost/ra/default.aspx:

I tried searching for that web.config file, but can't find it anywhere, and RA is installed under C:\NETQOS....

 

NPC is not installed yet, should I I go ahead install NPC to resolve this?

 

Thanks in advance.

Morongwa

[Christopher Walsh]

Installing NPC will not fix this.

Also if you will be upgrading to NFA 9.3.x you will need to have NPC on a separate server anyway.

 

That path seems strange, maybe it was leftover from a reinstall of RA.

Check the Default Web Site's physical path, as well as the other web site directories in IIS.

It looks like this error is looking for the SingleSignOn directory, so check that site to make sure its pointing to your SSO directory.

[Anon Anon]

Thanks Chris,

 

You are right, it is from an old failed installation that was overwritten later. It doesn't seem to want to remove the cached path for some reason.

 

I went and did a search fro SSO file, and found this file "C:\NETQOS\reporter\NetQoS.ReporterAnalyzer.WebService\SingleSignOnWS.asmx", so now  went into SinglesignOn Default Document Basic Setting and changed the path to be of "C:\NETQOS\reporter\NetQoS.ReporterAnalyzer.WebService". now getting.

 

I am avoiding to have to rebuild the server from OS without resolving this issue, but it looks like with all these issues that keep on creeping up I might as well just go ahead and rebuild the serer from OS, what do you think.

Do you have a working RA 9.0 server?  You can compare the IIS physical directories from that installation and set them here on this lab.

[Christopher Walsh]

Here are the path's from my 9.0 lab....

 

 

 

 

 

 

[Anon Anon]

Thanks Chris for Sharing the details.

 

I had a look at all the settings, I am missing SingleSignOn directory in my lab server and that is probably the issue here. Seems like the installation did not put SingleSignOn packages on the server during the installation, I might have to copy the files from my client's production server over to my lab server. Will that work? My client is on Win2003 and my lab is Win2008.

 

Thanks and regards.

I think a better bet would be to uninstall and reinstall since there could be a lot more missing.

 

RA doesn't have an unintaller so you will have to uninstall manually via the steps below.

 

Follow these steps to manually uninstall the product(s):

1. Log onto the server and stop all the NetQoS services, and Mysql.
2. Make a backup of the database as needed. If you aren't interested in keeping data, you can skip this step.
3. Remove the product related registry keys from HKEY_LOCAL_MACHINE\SOFTWARE\NetQoS. (it says related in case you only want to remove RA for example, but leave NPC in place on the same server)
4. For 64 bit systems, this is located in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NetQoS.
5. Remove the product related service keys from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services (These will be anything that starts with NetQoS and/or Mysql. This removes them from the services manager list of services.)
6. Reboot the server.
7. Delete the product related folders/files off the disk from the D:\NetQoS folder. (This depends on the product.)

Deleting D:\NetQoS is sufficient to completely remove the product files in most cases, but if you have NPC installed on the same server as another product, then you don't want to remove the NPC related folder D:\NetQoS\portal, nor the SSO related folders or web service folders, if you are not removing NPC as well.

Deleting D:\NetQoS will break NPC in that case.

Just remove the necessary folders for the product you are removing from the D:\NetQoS folder and leave the others.

Then delete all of the Websites from IIS so that the paths are correct during a reinstall.

 

Reboot the server and your should be good to reinstall.

Hi Morongwa, RA 9.0 is EOS, I would recommend you install the latest version of NFA instead.

[Anon Anon]

Hi Marlos,

 

Yes I know, but I am testing the upgrade that I need to do for one of my clients, they are still on 9.0, I need to document all the challenges that might come up so I know exactly what to look out for when upgrading the production server, that is why I am starting with 9.0, need to test that before we get to NFA 9.3.x because we do not want to loose historical data.

 

Thanks and regards.

[Christopher Walsh]

Morongwa, were you able to reinstall following the uninstall instructions above?

[Anon Anon]

Thanks Chris,

I have just re-installed today.

 

SSO files were installed this time under C:\NETQOS\ directory. I tried logging in, now I get the page cannot be displayed. Apon my investigations, I noticed I am missing Default Web Sites from IIS Manager.

 

Strange one

Morongwa

Something must have been left over from an old install before you reinstalled.

I would either open a Support issue so we can take a look or if you have the option to simply re-image the server and start with a clean server that might be a good way to move past this.

[Anon Anon]

Hi Chris,

I took your advise and re-installed the OS to do a fresh install. Thanks Chris for all your help, I now have a working system.
