This past weekend we decided to create a new database server and migrate the databases to the new server in an effort to retire an old box.
INitially we attempted to go through the configuration wizard which didnt do anything but add a new database server to our farm. What we have done is remove the new database server from the farm and use an alias on the SP server to continue to use
the same name but actually get its data from the new database server.
Everything works with the site except these custom webparts.
Any thoughts on where to go to first, should i redeploy what i think are the webparts from VS 2005 (solutions are VS 2005 slns.)?

You need to make Safe Control enteries in your web.config for the particular web application.
Open web.config
Locate the SafeControls Tag
Make a safe control entry
<SafeControl Assembly="Assembly name, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d8eb6481d8b4beec" Namespace="your webpart namespace" TypeName="*" Safe="True" />
In order to find the assembly details, Open the GAC. Right click on your dll and then click properties.

Hi,
After moving my files from SP 2010 to SP 2013 , for all my web parts i am getting A webpart or web form control on this page cannot be displayed or imported.The type could not be found or it is not registered as safe. error. I checked web.config files

These webparts work in 2010.

Hi Adit,
According to your description, my understanding is that the error occurred when you deployed the .wsp files to SharePoint 2013.
I recommend to check if all the assemblies are put into the BIN and GAC.
If above cannot work, you can check the troubleshooting steps in the link below:

Hi Ashok,
According to your description, my understanding is that you got an error after you re-built a SharePoint 2007 solution with VS2012, and deployed it.
Make sure the Namespace and Type Name are consistent across all files where indicated. Also with matching case sensitivity. Verify web.config file and assembly in GAC or virtual directory bin folder in post deployment.
More information, please refer to the link below:

"This page cannot be displayed error"

When I attempt to use the preview site feature, I am getting a "This page cannot be displayed smate sure the web address http//### is correct" error. Last night, I tried the feature and while it showed the page it only showed an earlier preview, none of my updates were visible. I'm thinking the two are related (Using Windows 8). Can anyone here give me a hand? Thank you in advance for your help.

I'm new to Muse and was having this problem as well. I came across this forum while searching for a solution. I solved my problem by opening internet explorer, going to the menu bar then Tools>Internet options>Security. In the Security panel I unchecked the box for Enable protected mode(require restarting internet explorer). This worked for me. I then turned the checkbox back on after I was done previewing my page. I'll just have to remember to do this while previewing my sites. I do have additional internet security so I'm not sure if I can leave this box unchecked all the time.

This page cannot be displayed - web connectivity problem

Just purchased an HP laptop with Windows 8 and IE 10.
I am connecting to my wireless connection because I can login and use Yahoo messenger, but cannot access any websites. When open IE, get the error: This page cannot be displayed.
There is an option to Fix Connection Issues - tried this and get the following results:
Problem with wireless adaptor or access point (not fixed)
Your computer appears to be correctly configured, but the device or resource (www.msn.com) is not responding.
Searched Google and there was a suggestion to flush the dns using command: ipconfig \flushdns. Did this, rebooted and then the home website does come up (www.msn.com). However, if I click any link on the site, I then get back to the same 'This page cannot be displayed' message.
Anyone else having this same issue or have any suggestions for resolving?
Thanks

I'm sorry your new laptop isn't working! I think I have some solutions for you and hopefully resolve your issue quickly.
(Make sure your time and date are correct!)
First, reset your router. This is done by unplugging the power from your router and modem. Once ALL the lights on both are out, wait a few seconds. Plug the modem back in, wait for the lights to come on, then the router. Give it time to access the device and assign IP addresses (this takes up to 4 minutes with some models). Once completed, try to reconnect using your HP laptop.
If that does not work, manually reset your IP address by using the command prompt (search for it using the search option on the right menu),
ipconfig /release
ipconfig /renew
This should flush the IP address. You have already reset the DNS, and you may do so again just to clear everything.
If that still does not work, hook the Ethernet cable directly into your laptop and see if it can get online. If it does, then it is a wireless connection issue and you should either return it OR have Geek Squad take a look. If it doesn't work, then either your router will NOT assign an IP address properly due to the computer having the same IP or Name as another computer on your network, or the computer could have a winsoc issue. In this case, you would have to restore the computer or
go to :
microsoft.com/fixit
And use there fix. Download it on another computer, burn to DVD/CD or drop it to a flash drive, then use it on the computer giving you the issue.
Let me know if any of these options work!

The page cannot be displayed while running the report with web link

Hello,
I tried to run the report using a web link similar:
http://hostname/reports/rwservlet?report=WRFTCKL.rdf&userid=use/pass@datbase&desformat=pdf&destype=CACHE&paramform=yes
I am able to see the parameter form, but after I entered some parameter and submit, I got an error as:
The page cannot be displayed.
But if I run it with the paramform=no and attached the parameter/value pair at the end of the link, the report will show on the web.
Anyone knows what is wrong?
Thanks.

LYNC 2013 control panel error: this page cannot be displayed

Dear sir,
Now i am suffering with the lync 2013 control panel problem, i cannot open it and got the error "This page can't be displayed" as below screenshot shows,
I've tried some ways, but still same problem
1. Reflush the dns, checked the A record and SRV record of the FE are normally.
2. checked the IIS and also cannot find any problem.
3, reboot the FE server/IIS, and AD.
4. i can open the console page normally via web :https://localhost/cscp
5. i can ping the FE server domain name and return the right IP info.

Hi TECH-Tommy,
The certificate is under “Personal” store.
In addition, can you open the page via
https://admin.domain.com ?
Also please try to clear IE cache and treat the FQDNs for admin, pool or FE server name as trusted zone.
Best regards,
Eric

Error: "Some controls on this presentation cannot be activated"

Hello,
A friend has sent me a Powerpoint presentation with an embedded Crystal Xcelsius ActiveX control.
On one of my PCs this displays perfectly, and I was on the point of buying the product when fortunately I got feedback from a number of other colleagues. Out of the six people I sent the presentation to, only one person could play it. All of the others experiences this error when opening the presentations:
"Some controls on this presentation cannot be activated"
I searched the forums and came across this rather brief description:
http://technicalsupport.businessobjects.com/KanisaSupportSite/search.do?cmd=displayKC&docType=kc&externalId=4360796&sliceId=&dialogID=12028678&stateId=1%200%2012034044
As recommended, I installed Flash Player 9 on one of the affected PCs, but it did not cure the problem.
On request, my colleague sent me versions of the presentation in Acrobat and Word and both of these files play on all the PCs. So for some reason it's only Powerpoint that won't work.
I'm very impressed with the power and beauty of Xcelsius, but it seems pointless to use something that can't be viewed by most of the people I'd want to see it.
Is there a better description of this problem? For example:
- How do I uninstall Flash Player 9?
- Where do I find Flash Player 8 (couldn't find it on the Adobe site)
- How do I "uninstall ActiveX"??
- If the Flash version is the problem, why does it work fine for Acrobat and Word? Surely this is a Powerpoint issue?
- If this is such a big problem, why is it not possible to select a target verson of Flash within Xcelsius (I've seen this feature in other Flash converters, such as Camtasia).
Details:
PCs are all Windows XP SP2
Powerpoint 2003 and 2007, and various combinations seem to share the problem
Flash Player 9

This is a Flash security issue and compatibility issue. If the dashboard is created and exported from a machine running Flash 9, then anyone who wants to view the dashboard will need to also have Flash 9. One solution would be to make sure everyone you may send it to has downloaded the latest version of Flash. The other would be to downgrade the Flash version on your machine to an older version. Crystal Xcelsius 4.5 requires at least Flash 7. Instructions for uninstalling your current Flash version and installing an older version can be found on Adobe's website. http://www.adobe.com/support/flashplayer/
Another cause of the error, could be the end viewer's security settings. Flash 7 and later versions have a security setting that require a cross-domain policy file. See the above website for more info.
Also anyone installing Flash must be sure that the Active X control is downloaded from an Internet Explorer web browser.

When this error occurs, there is nothing noted anywhere in the application log file. Where else can I look for clues to debug this?

Hi,
I would expect a HTTP 40x error or similar but no a page cannot be displayed as this indicates a missing or wrong page link.

Web Dispatcher - Page Cannot Be Displayed

We have a Web Dispatcher in a DMZ (DMZ2) that is used for external (Internet) access to our E-Sourcing application. The E-Sourcing application is in another DMZ (DMZ1).
When external (sell-side) users enter the url in their browser to connect through the Web Dispatcher over the Internet, the initial E-Sourcing screen is displayed very briefly in the browser and then the message 'Page cannot be displayed' comes up on the screen. If the browser screen is refreshed, the login screen is then displayed and the user is able to log in with no issues.
This occurs only when trying to access the E-Sourcing application through the Web Dispatcher. It does not make any difference if the Web Dispatcher hostname is used in the url (internal access through Web Dispatcher) or if the url created specifically for the Web Dispatcher is used (external (Internet) access through the Web Dispatcher). The result is the same.
If either http://WebDisp_Hostname (internal) or http://www.myESOapp.here.com (external Internet) is entered in the browser, both display the front-end ESO screen briefly and then display the 'Page cannot be displayed' message. Refreshing the browser screen then displays the login screen and users can log in OK.
Can anyone point me in the right direction to solve this? I have reviewed the Web Dispatcher trace file and the E-Sourcing log file and can find no errors or anything that would indicate what might be going on. It appears to be a Web Dispatcher issue. Any help would be appreciated.
WL

Hi Wayne,
When external (sell-side) users enter the url in their browser to connect through the Web Dispatcher over the Internet, the initial E-Sourcing screen is displayed very briefly in the browser and then the message 'Page cannot be displayed' comes up on the screen. If the browser screen is refreshed, the login screen is then displayed and the user is able to log in with no issues.
When first time you call URL , do you the page of Esourcing or you directly get the error page.
It better , install HTTP watch software on you dekstop and then activate the HTTP watch and start browsing the page and generate the problem which you are facing .
Once it is done share the result of HTTP Watch in the forum , depend upon that we can come to some solution.
Thanks

HP002264446493 HP002264446493
I think I have to add the SAP server IP
So I click at menu bar -> System -> Status and press Other Kernel info. (Green)
==>> I get Host = abcdev and IP address = 10.74.XX.YY
After that, I add the 10.74.XX.YY abcdev to be the last line.
Is it correct?
3. No data in table HTTPURLLOC.
4. ECC 6 and I never installed Netweaver.
PS. I create my own web dynpro but the layout is not working 'The page cannot be displayed' .
Thank you very much.

I change host file to 'abcdev.' but it does not work.
If I use command 'ping -t 10.74.XX.YY' , it's ok.
If I use ping -t abcdev.:8000, it's not working.
PS. IE version 6 and Connection -> Lan settings ==> Not set anything.
Help me please!!!
