"An error occurred in the communication with the BW server"

Hi, when I open BEx Analyzer and try to connect to my BW server to run a query, I get this message, "An error occurred in the communication with the BW server".
Can someone help me.
thanks
Pat.

If it's happening consistently, it could be a problem with your local m/cs MS office and/or SAP GUI.
If it was working before:
1) Uninstall SAP GUI and MS office.
2) Install MS Office and SAP GUI...then try to connect to BW.
Good luck, BB

Error message on iweb, no communication with server

I have three websites on my iweb and hosted by Go Daddy. The main site will not download, error message no communication with server yet other two work fine. I have been to Apple Genius and talked to Go Daddy three times and all is supposedly in order but still will not work. I am able to download on Cyberduck
but using Iweb would be so much simpler. How can it work on two websites and not the third? Help!

If the main site, with the URL - http://www.domain-name.com - is not downloading in the browser, it will be because the external index.html file is not present in the root folder on the server.
The other sites will work because they have the folder-name in the URL ...
http://www.domain.com/Folder-Name/
... where Folder-Name is the name of the site in iWeb.
Its just a question of republishing the main site if you are using the iWeb FTP and use the settings shown on this page....
http://www.iwebformusicians.com/iWeb/Publish-Website.html
If you can use an FTP application, publish the site to a local folder and upload the external index.html file only, to the root folder on the server.

Error when communicating with server, and locked fields

Hi there,
I am having a really weird, and annoyingly intermittent, problem.
I'm trying to write a single value to my application via an Input EVDRE, for testing purposes. I've been doing this all morning (admittedly to a different application set but still...) but this time when I "send and refresh", it takes ages before coming back with this error:
"An error has occurred while communicating with the server"
Further more, if I look at the table "dbo.lckFinance" there is now a locked field in the database for this specific category and time. So a user without access to a DBA (or the database, in my case!) would be stuck now - even if the communication problem was solved, they couldn't post anyway.
The application is not part of appshell, we are running BPC version 7.0.112 on SQL Server 2005.
I've looked in the Event Viewer on the server and found nothing untoward there.
Any idea what is happening and how I can avoid this in future? The communication thing is obviously a problem, but I'm just as concerned by the locking.
Please help!
Many thanks,
Jason

Hi Jason,
If you have problems with the network this has to be solved.
I don't think we can have a software working if a cable was unplug ).
We advice our customer to use citrix servers in case if the latency into network is high (more than 200 ms) and of course in case of loosing packages.
But I don't think the problem in your case is related to the network.
It seems in your case it was a problem of send governor.
This can have problem when the cube and dimension are not syncronize or you have an error in one of dimensions.
Also can you check the table sgqueue if you have any record there when nobody is sending data?
If you have records there then you have to delete these records.
Check also tbl"your application"lock if you have records.
Regards
Sorin Radulescu

Error Communicating with server

I've completed 4 projects and all went perfect without a hitch. On starting a new project, I created 3 new bins, audio, stills, video. When I clicked on capture, I get "error communicating with server. If this continues, contact adobe tech support." I can't figure out why I'm getting this message now. I haven't changed settings, using the same HD camcorder, etc.
Any suggestions?

Fast response ~ thanks. I'm using the same camcorder I used on all previous projects: SonyHandycam, so I know it's not the camcorder I've had no problem capturing in the past.
The project settings: General>Action Safe & Title Areas are default settings; 20 and 10: Video display format: Timecode: Audio display format: audio samples: Capture Format: DV. In the Sequence settings, they have to be factory default cause I've never changed any setting there.
Actually I'm really stumped cause I just finished my Grandson's graduation video on July 10 and Premier and Encore worked beautifully. Now, trying to do a family reunion video, I started new project, didn't change any settings, and when I clicked on Capture, it said "Capture Device Offline". I went back and replugged in the camcorder, and still nothing. Closed program, thought about it for awhile, then when I reopen, I get the "error communicating" in the resource panel.
I doubt this will help you but I'm hoping......

I get error message: "An error occurred with the publication of album...Authentication with server failed. Please check your login and password information" whenever I open a facebook file in my iPhoto. In each file, most of my photos have disappeared. I am hoping I can retrieve these "lost" files. What do I need to do?

Error message "unable to connect with server. Check wifi connection"

I started having the error message "unable to connect with server. Check wifi connection" when I attempt to use search function within a certain apps and when I try to download certain magazine (eg. National geographic). I didn't have this problem with I first started using iPad, and no problems with connectivity when using other apps. Can anyone help?

You may not really be connected to your WiFi network.
Your router may not have given your iPad a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPad (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc.

SCOM agent communicating with server?

Dear all,
After SCOM agent installation how that agent will start communicating with server? Is there any flowchart (like first how the communication will start , then when the MP will get download ..etc..)
Thnaks,

Hi,
The System Center Management Health service on each monitored agent collects performance data, executes tasks, and so on. Even when the service is unable to communicate with the management server it reports to, the service continues to run and queues the
collected data and events on the disk of the monitored computer. When the connection is restored, the System Center Management Health service sends collected data and events to the management server.

Error communicating with server when trying to download a score in soundbooth cs5

I recently am getting back to some projects of mine. I went into Soundbooth CS5, and the Resource Central lists all of the scores and sound effects available to me. It says that i'm online, but then when I try to preview or download anything it gives me the following error:
"We're sorry, but there was an error communicating with the server. Please try again and if the problem persists, contact Adobe Technical Support (0) ioError: -1"
How do I get at the scores and sound effects? Is there a way I can download them so that I don't have to consult with the server anymore?

Soundbooth is dead and those servers are offline most likely. I haven't seen any official note on this, but that doesn't mean it couldn't be the case...

Can't activate on mac 10.7 Lion-Error communicating with server

I followed help to remove former install and manually install; tried to sign in and activate get same error as when I also tried "don't authorize andactivate" which was: Error communicating with AdobeID server. Try again later. E_AUTH_BAD_DEVICE_KEY"
I'm getting VERY frustrated with this new LION OS on this mac. I can't use OVERDRIVE media-it won't work, I can't use ADOBE, it won't work. I'm about to take it back to where I bo't couple days ago and go back to iPhone which overdrive ALWAYS works and forget all else!
If ANYONE knows ANY solution, since it seems one can never talk to a LIVE person at ADOBE to get help, I'd sure appreicate it.

The way that it is supposed to go, is that when you Launch ADE for the first time, there is a system dialog that supposed to come up and ask you for your login password, so that ADE can get access to the keychain to add the "Digital Editions" password entry.
If you cancel out of that dialog, or don't enter in the password, then you will get the "E_AUTH_BAD_DEVICE_KEY" error.
Make sure that when you launch ADE that this dialog doesn't come up behind ADE (minimize ADE).

i am not understanding why it is getting for me, Please help me

Hello,
Whoever wrote the CustomCodeGenerator will have to help you with this one. We know nothing about the underlying code they are using and therefore can't determine the cause.
Appears the error is it can't even load the report so there is something wrong with the workings. Open the report again in CR Designer and Verify Database and then check the changes you did. Something is not right or the DB driver their application is using does not match with what you are using.
