DTRServlet - 500 Internal Server Error is returned for HTTP request

Hi everybody,
I've got a Problem with my DTR.
Recently we've set up the new CE 7.2 System.
The DTR has run until about 3 hours ago.
I don't know what I've done that this error occurs, but I'm nearly shure that I haven't done anything that depends on the dtr.
I went through the set up wizzard of "Connect Design Time for Visual Composer with NWDI" again, but nothing changed.
Can you please help me with this issue?!
Thank you and best regards
julian

Hello Julian
This is a known problem.
Cause
- A user may have been added to a group in another ldap tree with a name, that is already existing.
- When DTR retrieves the group from UME, we get 2 similar group names, but the groups may be different.
- DTR cannot handle this and throws "Internal Server error"
Resolution
If you change parameter "ume.ldap.unigue_grup_attribute" to 'uid', DTR doesn't use the groupname,
but the group-uid, therefore the group is unique.
1. open Visual Administrator
2. choose Services
3. choose UME Provider
4. Reset "ume.ldap.unigue_grup_attribute" with 'uid'
5. restart the system
Thanks
Kenny.

500 Internal server error on RPC over HTTP using TS Gateway

I've been happily using TS Gateway on Windows Server 2008 x64 for 18 months and everything was working perfectly. Suddenly this week it started giving "access denied" errors to any user who tried to connect, evidenced in event viewer as a failed login attempt.
After restarting the server, it got worse in that if I browse to the /rpc folder it gives me 500 Internal server error and I don't even get as far as authenticating credentials. I've tried removing IIS, RPC over HTTP and TS Gateway, and re-adding all of them,
but I still get the same error 500. The RPC and TS Gateway services are both running. What could be causing this and how can I fix it?

Hi,
Thanks for your post.
Firstly, check the following KB article to troubleshoot this issue.
This computer can't connect to the remote computer because the Terminal Services Gateway server is temporarily unavailable
http://support.microsoft.com/default.aspx?scid=kb;EN-US;969743
If the issue still persists, you may perform the below steps:
Uninstalled TSGateway, IIS role, all IIS related components.
Delete all files in the folder %windir%\system32\inetsrv\config
Delete all files in the folder %windir%\system32\inetsrv\metaback
Restart the server and try to re-install TSGateway again
Best Regards,
Aiden

Thank you very much for this. I confirm it fixed the problem, although there was an error in reinstalling IIS and TS Gateway until I also removed Windows Process Activation Service.

I get a 500 Internal Server error on EVERY non-https site I visit. Any suggestions?

I suddenly get this error using both Safari and Google Chrome, doesn't happen on Firefox, but I have other issues there. My new ISP, BT, say that it is a browser issue - so is anyone else getting this?
I am able to access any https site still.
Thanks!!

Yes i had this from day 1 with BT. The fools on their helpdesk said it was a browser issue. SO WRONG!!!
Can be fixed by turning off smart setup within the homehub itself.
1. Enter 192.168.1.254 into browser.
2. Goto advanced settings and enter admin password from your card.
3. Continue to advanced settings.
4. Goto Home Network.
5. Goto SmartSetup and turn off!!.
6. Click Apply
Job done. All devices should now work. Just wish the idiots on their helpdesk understood this and didnt waste 2 hours and 2 phonecalls. (maybe something stored on your devices if you had an older homehub....)

Hello everyone I am having a problem with sqlsrv_query I will be grateful to you please provide some help.
I am running a query through php:
$ls_parcel_query = "select * from ParcelDetail order by ExtractDate";
$result = sqlsrv_query($conn, $ls_parcel_query, array(), array("Scrollable"=>"keyset","QueryTimeout"=>300));
$no_of_rows = sqlsrv_num_rows($result);
echo "<br/>".$no_of_rows;
It gives (After 30 seconds):
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
I have php.ini settings like below:
max_execution_time = 90
memory_limit = 128M
While running this query in SQL SERVER 2008 R2, it successfully gives result in some times in 1 minute and sometimes in 2 minutes.

Workflow Manager for SP2013. The remote server returned an error: (500) Internal Server Error.

I am *almost* all the way through provisioning my on premise SP 2013 farm for SharePoint 2013 Workflows. Workflow manager is installed alongside Service Bus. Workflow Manager client is installed on the SP servers. I built a new simple list-based
workflow in SP Designer 2013, saved it, and published it without any errors. However, when I go back to the list in my portal and try to run the workflow, I get the "Sorry, something went wrong" page, and the logs say this:

Some sort of "general server error" returns a 500 code, but I can't tell from this what the problem(s) might be. Has anyone seen this before?
Thanks.

Go to the server running Workflow Manager and open the Event Viewer; Applications and Services Logs; Microsoft-Workflow; Operational; and look for the underlying error. In our case, the CU for Workflow Manager did something to the SQL permissions and
we ended up using the workaraound described here:

New Apache sites return 500 Internal Server Error for all CFML requests

This is an ugly one. I think it is an Apache2 - ColdFusion 9 web server connector problem.
I have two Solaris Unix web servers. Each of these servers have a dozen and a half Apache web sites each one connected to one of five ColdFusion instances.
All, but TWO of them are working properly. We created two new Apache web sites and connected them to a new ColdFusion instance. This worked fine on one of our boxes, the development one, but not on the other, production of course.
Whenever we try to request a cfm url from one of these sites on the production server we get a 500 Internal Server Error. HTML pages serve up just fine, and the new instance's Administrator runs fine on its 8305 port. So both Apache and ColdFusion seem to be working independently, but they are not talking to each other. All the other Apache sites connected to the other four ColdFusion instances also work properly.
This has led me to investigate the web server connectors. They have always been tricky and problematic to set up on these boxes. The built in tools have never worked for us on these boxes and we have always had to manually compile the connectors and configure the connections in the web sites..
But, as far as I can tell, all the connection setups are the same between working examples and these non-working sites.
Any insights into what else I should be checking and|or how web server connectors actually work (they have alwasy been mysterious black boxes to me) would be greatly appreciated.
TIA
Ian

Some more information.
I took a closer look at the logs (I wasn't looking
in the Apache logs before). I found this block for the last attempt to
request a cfm page.

When I connect to the SharePoint site that contains the lists I need to build my query from , Power Query enumerates the list and displays them in the tool. I can click on the system tables and view the records but any table

I can connect fine with InfoPath

thank you for your help
Andrew

Hi Andrew. In order for us diagnose this issue, you'll need to capture some network traces using a tool such as Fiddler and share them by sending a Frown.
To capture a trace using Fiddler, start Fiddler, enable the Tools > Fiddler Options > HTTPS > Decrypt HTTPS traffic option, start the capture, reproduce your issue, then stop and save the capture. You can find more information here.
Once you've done that, please send a Frown through the Power Query ribbon and attach the traces.
Thanks,
Ehren

Urgent help On as2 error The remote server returned an error: (500) Internal Server Error.

hi,
im configured the as2 partner setup as per this http://msdn.microsoft.com/en-us/library/bb246129(BTS.20).aspx.
but when im process file , then file try hit partner url goes dyhradated state,then failed. then i got below error.
The remote server returned an error: (500) Internal Server Error.
please any help..
Thanks

500 server error could be due to anyone of the following reasons:
Party configuration is wrong. Party properties/configurations have to be discussed upfront with the source/destination system and have to be in-line with
them.
Certificates have to be deployed in correct folders based on certificate types like private/public/signed etc.
Firewall (or network components) has to be opened accordingly for parties(systems) to interact. This change has to be done at the both the levels, source and destination.
If you receive it through HTTPReceive.dll (may uses this for AS2), you have to check its configurations.
Also 500 error, could occur even if your BizTalk artifacts has not been configured/deployed/enabled properly.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.
