Environment
ITMS 7.6, 8.0, 8.1, 8.5, 8.6
Resolution
How to determine entity size:
* Add extra logging in IIS to reveal content length of the request
* W3SVC log will start capturing additional info such as:
#Software: Microsoft Internet Information Services 10.0
#Version: 1.0
#Date: 2022-10-06 19:41:55
#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) cs(Referer) sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken cntlength

* This value is specified in bytes and will help to capture the size of request content for /Altiris/NS/Services/ItemReplicationWebService.asmx webservice when replication fails.
Please try the following:
Note: if this is happening during a replication or stand-alone replication, apply the suggested changes on both servers.
-
Open IIS.
-
Navigate under Default Web Site>Altiris
-
Scroll down to Management section in the middle frame and open "Configuration Editor".
-
Select following section (drop down at the top) "system.webServer" and expand it, then locate serverRuntime.
-
Find there the current value of "uploadReadAheadSize" value, which you can modify
-
Change it to 10485760(10MB) for example (or determine content size as explained above)...if it helped then we can try to decrease it until we find a smaller size (but still larger than the default 49152) that keeps the warning "The request failed with HTTP status 413: Request Entity Too Large." for happening.
-
After modifications please restart w3wp (from the command prompt, run IISRESET)
----------------------------
Additional setting which known to prevent replication due to entity size is system.webServer/security/requestFiltering
maxAllowedContentLength with default 30000000 value. Increase this setting accordingly.
---------------------------
NOTE:
If the suggestion above did not help then try to increase size of HTTP headers:
MS KB article explains all those settings:
http://support.microsoft.com/kb/820129
Create the following DWORDs, both with the value 65534:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters\MaxFieldLength
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters\MaxRequestBytes
