An error occurred while communicating with the remote host. Error code: 0x80070001
We recently moved our websites to new servers running Windows 2008 R2 / IIS7.5 and started getting the following error:
Exception information: Exception type: HttpException Exception message: An error occurred while communicating with the remote host. The error code is 0x80070001. at System.Web.Hosting.IIS7WorkerRequest.RaiseCommunicationError(Int32 result, Boolean throwOnDisconnect) at System.Web.Hosting.IIS7WorkerRequest.ReadEntityCoreSync(Byte buffer, Int32 offset, Int32 size) at System.Web.HttpRequest.GetEntireRawContent() at System.Web.HttpRequest.FillInFormCollection() at System.Web.HttpRequest.get_Form() at System.Web.HttpRequest.get_HasForm() at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) at System.Web.UI.Page.DeterminePostBackMode() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Specified method is not supported. at System.Web.HttpResponseStream.get_Position() at System.Drawing.UnsafeNativeMethods.ComStreamFromDataStream.Seek(Int64 offset, Int32 origin)
The error seems to happen in a rather random fashion on several different pages and we cannot reproduce it ourselves.
I am reviewing this site and others for similar examples but haven't found a solution yet. The general answer seems to be that it has something to do with TCP and / or VMware offloading. We're not using virtualization, so is this the only solution to disable TCP offloading? What will be the impact of disabling it?
